Doesn't fit 92 GTS
ISMI springs are great, but this one didn't fit my 92 GTS. It would install, but it's significantly longer and made for a far heavier trigger than what came in it. I'm guessing the twin sear design had an effect on the spring specs. I'm going to keep it around in case I get a more conventional Beretta 92 someday. 4 stars because the Pro Shop had speedy delivery and the part is as described.
