That's what I've noticed too Kevin. Never saw a comparison where a Glock won against a SIG. But I've never seen any endurance testing about the SIG. Apparently they can fire 10,000 rds. in one day w/o a hitch.
I've kind of become reinterested in the SIG 220. Which is a he!! of a comment from a die hard 1911 man. But the 220's just feel better in my hand. And shoot well too. For some reason, I don't get that with the lighter, smaller 1911's. The only exception is the Colt Defender. That one at least shoots well in my hands.
Heck, I've handled the "Carry", and "Combat" versions. I've shot the standard 220. While some of the testing done in some articles claims it doesn't recover or handle recoil as well as the steel 1911's, I've not found that so. It seems, if anything, to handle better in my hands. Both in pointing, coming on target and handling recoil. The alloy frame 1911's don't do these things as well for me.
So, I may well wind up buying one for carry purposes. E
