I understand the new Glock in 26/27 size is going to be available in .45 GAP shortly. I suspect SA will want to stay competitive & try to make the .45 GAP successful so as not to waste their investments to date.
The question is - is it a viable caliber is a short barrel gun, e.g., the SA SD Subcompact? Does the loss in velocity rendered by the shorter barrel make the .45GAP less than desireable? There lies the question. Seems like the impetus behind the GAP was to a large extent, ergonomics - SA and others can maintain thier current grip configuration - in the case of SA very popular particularly for those with small hands. But does it really make sense from a ballistics standpoint? Are there any published balistics stats comparing performance out of different length barrels?
Theoretically it should be more reliable than a .45acp from a short barrel. Hence why SA has come out with it in their mini 1911 platform. As far as velocity goes, a short barrel hurts all calibers. Worse case scenario it functions like ball ammo, if I am firing ball ammo I want it to be the biggest ball available. Best case, hollow points generate enough velocity to penetrate and expand. To me it would make sense to build this gun if for no other reason than to sell as a backup to those carrying the full size siblings.
