Folks, new gen 3 g19. 300+ rounds thru it no problems. Gun show last week. Certified glock armorer installed 3.5 lonewolf trg connector, extra power trigger spring, Glock extended slide stop, lonewolf extra large mag release. Shot 220 Remington umc thru it today. About 6 failed to load. Couple of stovepipes. Where to start looking for problem? Worried I've jacked up a perfect gun somehow? Thx for any help!
Thanks Vol! See the said "power spring" in the pic, on the right. Pretty sure it's a trigger part. Got the old parts still. Guess it was a $50 lesson - not to mess with a good thing? Are they fairly simple to replace?
