I A Sig 226 chassis (M11) will take a .45 barrel, which you can then load with hollow points. Beats the 9mm and ball rounds we're given.
The M11 is actually a Sig P228, the compact version of the 226. And I dont think the 226 "chassis" is able to be converted to .45.....Sig just designed the single-stacked P220 instead.
Nittany pointed that one out, P220 compacts would be a nice addition to the flight gear. Too bad the AF is the branch actively pursuing the .45 as a side arm again. When it comes down to using FMJ as the law states, .45 is a better choice in general.
...not tryin to further the .45 vs 9mm debate. My personal defense weapon is a 9mm Glock 19 w/ Federal Hydrashocks.....and a nice 12GA Mossberg
