When Star Wars was first being developed, the blasters were developed from real-world firearms.  Now real-world firearms are looking more and more like Star Wars blasters.

 
I find that interesting.  Perhaps George Lucas was right all along--Ya Think?

You're in luck, as you can readily purchase a Chiappa Rhino, which fires from the bottom cylinder like Vash's gun.

Here's a link to a read on it, since you seem interested: https://www.guns.com/news/review/gun-review-chiappa-rhino-revolver-in-357-magnum

Well, since the Focus is typically the gun, the ammo usually ends up being nothing more than a special effect to properly represent the Charges/Jammed/Burnout limitation(s) as taken on the Focus.  As far as different ammo types on a Focus, that's usually represented by either a MP or a VPP on the Focus ... with Extra Time (half phase, only to activate) to switch slots or change the pool (to represent a magazine change to one holding different ammunition) ... and Charges on the slots or the specific VPP power (to represent only so much ammunition of a given type within the magazine(s) represented by Charges on the slot or VPP power).  Many a GM will allow Fast Draw to apply to the Extra Time ... since it represents a magazine change (and since Fast Draw is capable of mitigating the usual half phase mag change).
 
But to be fair, there's really not a huge variety of ammunition for most small arms.  Caliber tends to dictate capacity (since bigger rounds take up more space and weigh more) ... and once the caliber is chosen, capacity only varies based on how much extra weight/bulk you want to carry in terms of magazines.  i.e. It's not like there are a plenthora of options to choose from within most given calibers.  I can't just run out and buy .45 ACP armor piercing rounds ... or .45 ACP incendiary rounds ... or .45 ACP penetrating rounds ... or .45 ACP explosive rounds.  Instead, my choices are basically: wad cutter, full metal jacket, hollow point, and match grade ... with a special note for tracer rounds.
 
Using the .45 ACP example, in game terms, full metal jacket is likely the de facto standard on which the .45 pistol's damage is centered (which I'll express as Xd6 RKA) -- i.e. no delta and nothing special about those rounds.  Hollow points probably takes that .45 ACP from Xd6 RKA to Xd6+1 RKA ... while wad cutter/match grade are geared for competition shooting (the former intended for punching very clean holes in paper ... while the latter is constructed for improved ballistic coefficient/aerodynamics) ... and, thus, each is probably something closer to Xd6-1 RKA in terms of output.
 
Regarding the tracer rounds I mentioned:
There -are- tracer rounds, but they tend to be available only in calibers commonly used by the military -- are spendy -- and are tough for non-military folks to get because they're just not that common.  These guys sacrifice pretty much all of their damage by burning their material as they fly -- to allow the user of the Focus to roughly see where s/he is shooting. By and large they are used as either training aids (for night ops training) or are staggered (as in every 3rd or 5th round) in magazines (or belts) of autofire weapons that are intended for high volume shooting at night -- to help improve night shooting accuracy (via night shooting penalty reductions; I'd represent tracers with PSLs to offset penalties imposed by natural darkness - that only work at night or in similar situations)  .... when/where FLIR is not available.  They also have the side effect of giving away the shooter's position -- so no using Stealth with tracer rounds at night once the shooting starts.
 
Additional note:
Bullet weight (heavier versus lighter) within a given caliber doesn't tend to mean harder hits ... instead, it tends to be a tradeoff between speed/trajectory and wind resistance of given caliber bullets.  i.e. A lighter bullet of a given caliber shoots faster and flatter than a heavier one of the same caliber ... but a heavier one of the same caliber is not as affected by the wind and retains more of its energy at longer distances than its faster/lighter brothers of the same caliber.  Thus, I don't see stun multipliers or BODY damage changes as germane to the bullet weight conversation within a given caliber, since bullet weight within a given caliber choice is mostly about accuracy under certain circumstances ... and we're talking a +1 to offset range/wind modifiers, tops here ... only at and between very specific range thresholds for given calibers (i.e. immaterial at short distances for given calibers).
 

See where this is going?  Most of the real meat/potatoes of guns are in:
caliber choice -- which will tend to dictate damage output optic choice -- which will tend to offset range penalties quality choice - which will tend to dictate whether the focus has an activation/jammed/burnout roll slop (i.e. tolerance) - this one's kind of weird and represents a tradeoff between accuracy and reliability.  The AK-47 is a great example, you can let it get dirty, treat it badly, and it will be super reliable despite its low quality and cost ... but to do this it has sloppy/loose tolerances that result in a less accurate firearm than, say, the M16 (when it is clean, anyway).  You can tighten those tolerances, of course ... and when you do so, you'll sacrifice reliability to gain back some accuracy.  
Now if you want to go crazy and make up a bunch of guff (akin to Green Arrow's quiver of totally ridiculous arrows) ... then you'll basically be creating a pile of totally ridiculous ammo for your game -- i.e. stuff that's just not out here in the real world.  A great example would be the tranquilizer bullet (from the XXX movie) ... or the splatter dart bullet (from the same movie).  That's bogus stuff for Hollywood's sake.  Sure, there are tranquilizer guns ... but they are specialized guns with specialized darts ... that use blanks or compressed air to propel the darts.  i.e. Someone didn't just pop some special ammo into a typical gun to get a tranquilizer round; they used a special gun with special darts.  (i.e. Different Focus, entirely...)
 

I've read about the Heizer PKO45's. The 8lb SA trigger is kind of a turn-off, but the 0.8" thickness is a selling point for those who want to pack .45 ACP in a slim package.  It will be interesting to see what the 9mm varietal's dimensions are, since modern 9mm single-stack offerings have been at the 0.9" thickness for nearly a decade, already.

Today I bring you the LMT CSW, an integrally-suppressed confined space weapon (CSW) chambered in .300 AAC. Your military-equipped personnel will appreciate the reduced recoil, muzzle flash, and noise levels that come with this 24inch OAL rifle when using it to defend confined spaces such as bunkers, ships, and similar locations. The platform easily meets SOCOM’s SURG ("suppressed upper receiver group") requirements and passes the SURG high performance stress test, offering rifle caliber force in a substantially smaller, suppressed profile. 
 
Spare no expense when it comes to the lives of your men; give them the equipment they need: the LMT CSW - for the ultimate defense in hyper-close/confined quarters.  Starting at $3999 per unit...
 

 

S&W 629 .44 Magnum Performance Center Edition (with a crappy UTG optic that comes with it; I think they should and could have done better than this).  This one's for the modern-day gunslinger in your campaign...
 

The GSL Pillbox appears to rely on wipes, which is basically Vietnam-era tech (with modern materials used for the wipe, of course).  I can't say I'm a fan of wipe-based suppressors given that wipes must be replaced -- usually within 3-4 magazines worth of ammo in order to maintain the same effectiveness as they had with the first round fired.  The fact that the wipe changes over time (due it being shot through) and the fact that the exiting bullet touches the wipe … always has me wondering what wipes do to POI, especially over time/reuse of the same wipe.  Still, it's interesting to see a suppressor THAT small!

Well, Jerry Miculek, is fast with what ever he shoots. This is him setting a worlds record
 
 
 
and here is some f him with a Semi-auto, specifically an M-1 Garand.
 
 
Enjoy!

Sure -- if using K11's or K31's!
 
The Schmidt-Rubin K11 (and later, the K31) are Swiss-made, straight-pull bolt action rifles designed by Rudolf Schmidt, a mechanical engineer who understood that two motions (pull back, push forward) instead of 4 motions (lift up, pull back, push forward, push down) would result in a halving of the time to actuate the bolt … thereby nearly doubling the rate of fire with no change in or loss of accuracy.
 
In addition to the straight-pull bolt, these rifles also have amazingly crisp triggers and free-floated barrels.  Considering the K11 was first produced in 1911 and was arrived at from improvements on designs dating back to 1889, the K11 was revolutionary in terms of speed and accuracy in bolt-action guns of the day.  The K11 easily put Lee Enfields of the same era to shame … without really trying.  Aside from the really long takeup on the K11, the crispness of the 100+ year old trigger on my own bone-stock K11 actually puts the non-adjustable triggers of most modern rifles to shame, too, IMHO.

The downside was the cost and complexity to manufacture the rifle … which is why this type of action likely isn't common, today.  The Swiss, of course, did it both right … and well.
 
 

This article was somewhat comical.
 
From the article:
Integral suppressed basically means the suppressor and barrel work together to make the suppressor perform better, it reduces the speed of the bullet to below the speed of sound. (The speed of sound is about 768 miles per hour at sea level) and for the record, James Seto has been heard many times saying, “It’s as quiet as a mouse fart.” )
 
I hate to tell these people, but the suppressor and barrel aren't magically working together to achieve better performance.  Instead, the barrel has been ported and the suppressor mounted over the ports in a way that reduces the speed of supersonic rounds to subsonic speeds thanks to the reduced gas pressure behind the bullet as it is expelled from the barrel.  That's not better performance, at all, it's just a means of rendering the shots super quiet (due to the elimination of the supersonic 'crack' produced by breach of the sound barrier) when supersonic ammunition is used.  It's a very SPENDY way to do it, too, since a regular suppressor that's not welded to the barrel atop ports in the barrel (which can be used on different guns BECAUSE it's not welded to one gun) … can achieve the EXACT same effect as long as the user of the firearm selects 147gr 9mm ammunition, which is subsonic.
 
Cute 9mm carbine … but it's ultimately a solution in search of a problem, IMHO.
 
Surreal
 
P.S. I have an integrally suppressed .22 rifle -- purchased specifically because .22 subsonic ammunition is more expensive (for less powder charge) than the supersonic rounds … and because .22 subsonic ammunition often has issues cycling .22's semi-autos.  Thus, I looked into a solution that would be super quiet despite use of supersonic ammunition, which I wanted to use to ensure the action cycled.  147gr 9mm ammunition that is subsonic has no such issue, as it typically costs the same as 124gr supersonic ammunition … and it reliably cycles 9mm semi-autos.  

Given your 'significant range' remark, I get the sense you feel I'm worried about the wipe having only minor alterations of POI (which, of course, become more pronounced at longer ranges).  While this is, of course, a concern due to 'normal' contact between the bullet and wipe as the bullet passes through the wipe, it is the 'abnormal' contact that most worries me.  The primary example of such 'abnormal' contact is when a chunk of the wipe breaks off during bullet/wipe contact -- which happens fairly regularly after the first mag or two is fed downrange.  Because the amount of the wipe that breaks off tends to vary … and because it's unclear how much of it adheres to, unbalances, or otherwise affects the bullet -- POI shift would seem to be a major concern.
 
It's a non-issue for minute-of-badguy shooting at any given distance, but if you want to punch paper quietly (which is what I consider most .22 shooting to be good for), it's something that I'd be prone to considering and worrying over.

A suppressed 9mm CZ Scorpion Evo 3A1 with short barrel and folding stock.  Hey, you said cost was not a major factor ... and this isn't something I can afford in any variant except the civilian CZ Scorpion Evo 3S1 varietal.  Worth a quick look:

 
P.S. You said personal defense; you didn't say what kind​ of personal defense!  Obviously this wouldn't be holstered, but belongs more on the homestead.

I've had the DP-12 in my hands and man, that thing is monstrously large/heavy compared to, say, the KSG.  It's also strange only having to pump every other shot.  Personally, I don't care for the DP-12.

Crye's Six12 is also an oddity as a standalone shotgun -- primarily because the cylinder is awkward.  However, it's insanely cool as an under-barrel shotty mated to an AR-15 platform.  Here's a taste of that:

 
 
And then there's the American-made UTAS XTR-12 AR-style semi-automatic 12 gauge.  No Saiga clone, here.  I can only imagine this thing with a Slide Fire stock and a 24 round drum mated to it.  And you just -know- someone will make a drum for it...



 

Today I bring you The Big Bang Pistol Set by Cabot Guns.  Fashioned into a pair of 1911-style pistols from a meteorite that was billions of years in the making, your Filthy Rich hero can have this set for all of his/her demon slaying and/or alien defense needs for a mere US$4.5 million.  A unique gift with a finish the likes of which you won't find anywhere else on planet Earth, The Big Bang Pistol Set -- for the discerning hero who has everything...
 
 

 

 

 

And for something completely different, here's a 2-man, crew-served gun with programmable 25mm airburst grenade capability.  The XM307...
 

So this has been around for a while but never had much 'splash'.  It's the CZ Bren 2, a 5.56 NATO chambered sub-machine gun featuring a super-short gas system allowing it to work well with barrels as short as 8 inches -- when suppressed. Weight is 7.5 lbs; magazine capacity is 30; and the rate of fire is 850 rounds/min.

Start at 1min on each of the videos, as it's all useless chuffa up to that point in each video:
 

 

The full barrel recoil system to which we are referring was CLEARLY employed to make that .50BMG platform man-shoulderable and man-fireable; nothing more.  If you think about it, that system makes little practical sense, since no sane, long-range shooter will use it to take long range shots from an unsupported, standing position with a shouldered rifle -- because too much accuracy is lost in a standing/unsupported, shouldered position.  Thus, the moment you put that platform down on the ground to get support from a bipod, you might as well have simply had a bipod and brake combination ... and a simpler platform that is less prone to failures thanks to reduced complexity. 
 
With that in mind, I feel a full barrel recoil system on a .338 Lapua platform is even more of a solution in search of a problem, as there just isn't that much recoil to mitigate with .338 Lapua.  In case you doubt my 'solution in search of a problem' assertion, here's a youth shooting a suppressed .338 Lapua rifle with a bipod. Do you see any need for a full barrel recoil system on that rifle??  (I sure don't!)  Do you think follow-up shots are a problem on that rifle? (I sure don't!)  Change the platform from a bolt gun to a semi-auto and you'll have quicker follow-up.  Eliminate the suppressor and use a brake, and it's still VERY tame compared to .50BMG...  (For reference: .338 Lapua produces only ~3 times the recoil of a 7mm REM MAG, which is quite manageable.  .50 BMG produces a bit more than ~6 times the recoil of .338 Lapua ... i.e. ~18 times the recoil of 7mm REM MAG.)
 

GM6 Lynx .50BMG bullpup semiautomatic rifle with awesome full-barrel recoil that looks painful to shoot
 

Ok, so this isn't actually a gun/firearm ... but the X15 flamethrower has a trigger, destroys things, is theoretically 48-state legal (note: I am not an attorney; consult your own for legal questions you have), and Internet orderable.  Recommended fuel mixture appears to be 90% diesel and 10% gasoline. It holds 3 gallons of fuel and uses a 20oz refillable/changeable CO2 tank to propel the fuel from the nozzle.  3 gallons will net the user about 1 minute of flamethrowing time ... slightly more if using their napalm mix (additive) -- which supposedly yields tighter and longer flame streams.
 
Price point is USD$1600-$1750.  Outfit your mooks today!
 

Here's the MCX Rattler -- the latest from Sig Sauer which it's billing as 'the world's smallest rifle'.  Currently available chambered in .300 BLK, which it will readily cycle whether suppressed or unsuppressed.  There's a 5.56 NATO version coming, but I think they got their default chambering right the first time on this one.
 

The mdr, with suppressor, on full auto...

A pop-up turret only makes sense when you want/need a heavily-armed (and usually armored) vehicle that doesn't freak out drivers of most other vehicles around it.  (Obviously air vehicles can tell.)  Private security organizations are the most likely consumers of such a mount.  Check this video out, especially from 1:19 to 1:48 relative to my remarks.
