I went to a local gun shop, and I tried out the triggers on a few guns, including a 686+, a Ruger gp100 and a sp101. For some unknown reason, I couldn't pull the double action trigger on the s&w, but was able to on the rugers, the 101 having the easiest trigger pull, which is strange in of itself. All the guns were brand new, and the guy behind the glass had no trouble pulling the double action trigger on the s&w. Can anyone think of an explanation for this?
