SigSauerGuns.com reports that SIG will be unveiling a new double stacked .45 ACP pistol called the SIG P227 at SHOT Show.

The P227 is going to be a .45 ACP double stack pistol with overall dimensions very close to the P226. The thickness of the grip will be pretty much identical to a P226 with 2 piece grips except it will be an enhanced ergonomic grip.

The P227 will ship with a 10rd flush fit magazine and there will be a 14rd extended length mag as well.

The P227 will accept standard P220 5″, 4.4″, and 3.9″ slides. If you have a P220 Match Stainless Elite or a Super Match, those slides should work too. The pistol will fit in standard P220 and P226 holsters.
