Belleville Shooting Range (in IL) finally got a S&W 1911 in, and I must say the trigger is ruined only by that stupid safety system. You can actually see the trigger move back a little bit once you depress the grip safety. The grip safety by far requires more force to depress than any other I've ever tried. Once the safety's depressed, the trigger itself isn't all that bad in my opinion, but you do feel the take up from the safety. When you depress the grip safety alone, you can see the trigger move back a little bit due to the safety being disengaged.
All in all, S&W did everything right about this gun, except for the stupid and strange safety system. They put a stainless steel bushing, barrel, slide and frame on it, along with an external extractor (non-Glock though...). The barrel/bushing fit was very tight, and there's no doubt that the gun is a damn tack driver. However, I don't understand why anyone perceives the need for an extra safety on a gun like the 1911, since it's impossible to fire the damn thing unless you depress the grip safety to begin with and unlock the thumb safety!!!!!
I think someone quoted Col. Cooper over on the 1911forum about the Series 80 type safety thing as a "solution to a problem that does not exist". I wholeheartedly agree with this remark, and I advise someone looking into a 1911 to seek out a Series 70 system. A Springfield Mil-spec or a Caspian slide and frame with an external extractor would be a great starting point.
