I'm not sure the bullets will stabilize in a shorter barrel unless you're using short ones like the TCM uses.
The cool thing with the S&W is the two piece locking barrel along with it being gas operated instead of delayed or just blow back. Unfortunately It isn't legal where I live and probably won't be until the gun gets more popular (which it should if what I've read about it is true).

No one is making compact versions of this. The PSA bbl is 4.7", the FiveseveN is 4.8", the Ruger is 4.9" and the S&W is exactly 5".

Pretty much everything else is that or longer. The Excel Arms MP-5.7 (pictured above) has a bbl of 8.5". The Diamondback Tactical Pistol DBX57CFB bbl is 8.5". The CMMG Pistol AR's in 5.7 are 5" exact, as is the Masterpiece Arms. The P50 is 9.5"

I think the only handgun in 5.7 which is seriously below the 5" mark is Excel Arms' weird X-series, originally chambered in 9mm, which bears a superficial resemblance to the TEC-9. It has a 4" bbl.

So if you're desire is for about a 5" bbl or better, then buy pretty much anything and you'll get what you want. :)

I wasn't looking for "compact" here. Only how it would be great if Excel made a shorter barrel version. Roughly 5 in...I know the FN,Ruger,PSA do not use exactly 5 inch . Any sub 4 in tube imho creates more issues than it solves.
This looks great. Now if they would only make one with a 5 inch barrel like the others do... This is no edc .
I have an IWB holster that allows me to carry either my FN or Ruger with an optic comfortably and they are both full size. The Ruger is thinner so it fits easier. I actually prefer the beefier grips on the FN but I know a lot of people don't like it. I put a universal sleeve on the Ruger cause the grips were too skinny for me.
This intrigues me, threaded and optics ready are appealing. But is it worth the premium over the PSA offering given my reluctance to shoot a high volume of 5.7? I dunno.

I dunno but I think it's pretty cool.

After shooting the FiveseveN once several years ago and shooting my new PSA, I'm convinced that the gas system isn't needed to manage recoil for the shooter. What recoil? If I were to guess, I'd guess it's to manage the issues surrounding the little 5.7x28 cartridge being comparatively high pressure for such a small package. It has a reputation of being almost thin walled, having the shoulder moving forward a lot due to the firing and extraction process, and having case separation after comparatively few reloads. If this gas system delays the extraction and reduces stretch then it could be a dream for 5.7 reloaders.

OTOH, maybe it's just S&W stretching their creative legs and proving that they can innovate engineering with the best of them.

In any case, it's pretty cool.

I might give it a look-see if it's available as a rental to see how it compares to my Ruger 57
If I hadn't picked up the Ruger last year I'd definitely be tempted to try the S&W. The barrel is intriguing. Either way I hope more people take up this caliber and drive down ammo costs.

Uh, I mean, you could just use a faster twist... Some folks are indeed using 5.7 as an EDC, but they are few & far between. Shorter bbls will likely significantly drop velocity, which is the cartridge's raison d'etre.

One big upside to the S&W, & I think I see three disadvantages.

The rotary bbl gas operated locking system, as Kirk noted, will likely ease working of the brass for reloaders, which would significantly drop costs for those folks, particularly if the S&W is coating agnostic, which it might be.

Downsides:

1) The rotary bbl & gas operated action is likely to complicate suppressor installation, unless Smith's gone with a fixed thread on the outer gas sleeve, but we still don't know what additional backpressure will do to the action.

2) Proprietary mags - most other manufacturers have a mag that fits an existing 5.7 carbine on the market, Smith does not yet.

3) Cleaning - looks simple enough, but reloaders may find certain powders are cleaner in the Smith's action, and casual shooters may find certain commercial loads are cleaner or dirtier and require the Smith to be cleaned more often than other action types.

So far as item #1 goes, from what I saw in one review the threads are on the outer barrel sleeve and it doesn't rotate.

That's really good news. Might be able to use .22" cans that are proofed for 5.7 w/o a booster then.
Heck, I'll put the threaded barrel on my Ruger even without a suppressor just for the extra half inch it adds. On a 5" barrel that's 10% more.

Yes, exactly. But the way the barrel works looks very cool and I will bet accuracy should be very nice keeping the barrel from "tilting".

But I agree that it brings something different & innovative to the 5.7 and handguns in general. For that reason alone makes me want it... damn PSA!!
