Gen 3 Glock with Caspian slide, KKM barrel, Zev Ultimate trigger/ #3 spring just won't fire. I just put it all together and the striker is hitting the primer but not hard enough to ignite the primer, I didn't try the 2# spring. I put a stock G22 trigger group and stock striker/spring in it and still no bang! When I first bought the used slide I put it together with stock parts and got off one round then light strikes, sent the slide off for serrations and ceracote and had high expectations but no love. Ammo is factory. I'm really at a loss of what to do next, any help would be greatly appreciated!
