[QUOTE="Rod Snell, post: 151012, member: 796"] I use SW9VE's for intro to semi-auto trainers (yeah, REALLY basic stuff), and would love to get one with a G34 trigger: not going to happen. I had a long talk with the MA IDPA MD who works for S&W on the potential hazard of a mod to the Sigma that does reduce the trigger pull about 1/3. (It showed up on the internet). As long as no +P+ ammunition is shot in it, the gun functions with the mod. The failure mode if the hot ammo is shot is that the trigger does not reset because the slide returns too fast, and the gun will not fire until the slide is pulled back to reset. So, for IDPA rules, the mod is legal. Obviously, it would be unacceptable to do this mod for a defense gun, and neither I nor S&W recommend it. Basically, S&W designed the Sigma for standard SAAMI ammo, and when people started shooting +P+ ammo and failing to get sear resets, S&W added an extra sear return spring around the first one. Instant extra-heavy trigger pull. Remove the outer sear return spring, and you risk the sear not resetting. [/QUOTE]
