Just to pass on my perspective....... I've had 5 different 1911s over the years, a Gold Cup National Match, a MkIV Series 70 Gov't Model, a Series 70 Combat Commander, a Norinco clone, and finally a Wilson Combat CQB. NONE of these (some with considerable tweaking) were ever reliable enough for defensive carry. The Wilson CQB comes close. I haven't been able to make it choke on factory ammo, but the tight chamber means that I REALLY have to take pains on making reloads for competition.
I've had a lot of different handguns over the years, and when it comes to protecting me and my family, there is only one that I'll trust. Glock.
