So far 1000 rounds through the pistol and not one malfunction The only things I am going to do is get the all stainless form galloway performance and a stainless steel striker fire indicator. I do not like how the spring on the guide rod looks like it is bending like there is too much spring there or something. I have had a few people tell me to take out the mag disconnect it caused them problems after watching them shoot they do not know how to put a magazine in. After spending some time in the military it is natural for me to slap the magazine as I put it in. With the guide rod it my just be my OCD kicking in (that is what the boss aka the wife says)
