I recently acauired a S&W Sigma. I went out shooting on Saturday and it wouldn't reset the sear and or hammer after the first shot. I inspected it and noticed a spring out of whack. I got from a friend who originally purchased it off Gunbroker. The original owner did a sear polishing job and didn't put a spring back. Anyway, found a temporary replacement, and it shoots great. I do like my Glock though, it may be 5+ lbs trigger pull, but, it does break like glass and it doesn't require a long travel.
