I recently purchased a new G34 and (although it's admittedly not broken in yet) noticed that it will not cycle properly with the 115gr plated / 3.9gr TiteGroup reloads that work wonderfully in my G19. A couple of the better shooters in our local gun club's steel challenge competition have encouraged me in the past to purchase a lower weight recoil spring for my G19, but I think that's a mod I'd be more interested in doing on the G34. I'd prefer to avoid the expense of purchasing 11, 13, and 15 lb recoil springs just to see which one works best (although I recognize that might be the "right" way to do it). So I'm wondering if anyone can suggest a good starting point if I were to only purchase one of the three lower weight recoil spring options. I performed a forum search and really only found one other relevant thread, but it didn't provide a sufficient answer to my particular question. Thanks in advance!
