Just installed the Lone Wolf Dist's 3.5 lb connector in both my glock 21 and the wife's G19. when i sent my G21 in for the frame rail "upgrade " a couple of years ago. i thought the trigger pull felt heavy. when i sent it i it had a factory 3.5 in it. Well i figured they had the 5lb one in it . it wasn;t till i got the 19 and felt the difference and pulled the one out of the 21 that the little stinkers put a 8lb lol. well i sent the wife in to the gun store and she picked up 2 Lone Wolf Dist's 3.5 lb connectors. big change. any way does any one have any input on these connectors "I won't be wronged, I won't be insulted, and I won't be laid a hand on. I don't do these things to other people and I expect the same from them."
