Just when I think I can’t be surprised, I get an e-mail about the new SIG SMG.  The new SIG SMG is a submachine gun being introduced by SIG Sauer at the 2013 SHOT Show in Las Vegas.

The SIG rep I corresponded with advised the new SMG is very innovative, with an easy to learn system, great ergonomics and AR-15 style controls.

According to the photos I have seen, it looks like the SIG SMG has a folding, collapsible stock, a full length Picatinny rail for sights, a quad rail fore end, and an AR-style flash suppressor.  The bolt release, pistol grip and selector switch all look very similar to AR controls.

The uppers will be changeable in a manner similar to the AR platform.  This will allow the shooter to swap calibers and barrel lengths.  Initially, the SIG SMG will be available in 9mm, .40 S&W and .357 SIG.  According to SIG, the gas system is self regulating and can handle swaps between the above calibers without problems.

I am told there will be three versions of this gun (not including the different calibers.)  A full-auto version will be available for military and law enforcement.  Two semi-auto versions will also be made for civilian purchase:  an SBR (short barrel rifle) and a 16″ carbine.

I expect that the gun’s barrel is threaded for the easy addition of the upcoming SIG suppressors.

I imagine this gun is a screamer with the .357 SIG rounds loaded.  The bottlenecked SIG cartridge offers a significant step up in velocity when compared to the 9mm, and in an SMG, I believe this would be an awesome CQB round.  Although not designed to do so, the .357 SIG would likely defeat soft body armor, while maintaining the gun size benefits associated with a pistol caliber SMG.

Many law enforcement agencies have been turning in the MP5 SMG and going with short barreled AR-style rifles.  While the 5.56 offers some distinctive benefits for an entry team, a more compact SMG loaded with .357 SIG might be a good step up from the MP5 without running into some of the negatives associated with the very short barreled AR guns.

According to the company, the new SMG is still without a name.  They could go with the SIG Sauer Ass-Kicker or the SIG Blaster, but I expect they will use some number for a model designation like “P226″, “P238″ or “Seven of Nine.”
