My favorite 1911 I've ever shot was the Nighthawk Custom T3. Not a year later, I shot the Sig C3. I was very impressed. I looked at it kind of like a "poor" man's T3. I then shot another Sig 1911 of the same size (don't remember the model name). Even more impressive. I've decided to get one as soon as funds permit. Hopefully, that will keep me satisfied until I can afford my very own T3.
Since then, I've shot the XO and another railed Sig. I haven't had anything but good experiences. As much as I love my STI Spartan and Para GI Expert, I'll probably sell one to help fund my Sig purchase. So, if you couldn't tell by now, I'm a big fan.
