I think it really depends on what you want to do with the gun. I have a 5†1911 in 45 that I compete with and a 3†Colt 1911 45 that I carry. Like Tag says the recoil from the little gun is sharp, in fact it’s not FUN to shoot at all. Reliable (I trust my life to it) and small enough to hide, for me, it’s the perfect carry gun. But if you just wanting a gun to take to the range and have some fun shooting or something to leave on the nightstand for those things that go bump in the night, then I’d buy a full size.
