Tough call..... many fine weapons listed there... . but I'd have to go with the 1911. No complaints with just about any ammo, while some upper end 1911s have issues feeding at times with certain ammo. While the overall accuracy will not be as good as the upper 1911s, or the Sig, the overall function and reliability is legendary. Just ask any WWI(the one surviving) veteran, or any WWII vet..... reliability in all conditions is a must. Accuracy is not as good, but when confronted with a bad situation, "minute of torso" accuracy is more critical than MOA... ...
