Ran into a bit of a problem with my new Glock 23 about 3 weeks ago. First time at the range I went through 70 rounds of two kinds of ammo. One was UMC 180gr JHP and the other was 180gr TulAmmo. Had about 4 times where the slide failed to go into battery by about 1/16". A quick nudge with the thumb sent it home. Three other times, I had a light strike. I just pulled the slide back enough to reset the striker and it fired the round. Now, it pains me to admit it, but I had gone to the range on an impuse and realized there, that it was just like it came NIB, i.e. no lubrication. The only thing I had done was put in a LWD stainless steel guide rod. So now, I would like to get some of the wisdom that is always available from a forum. Have wondered if these are "limp wrist" symtoms or could the LWD rod been a problem. Would a new, unlubed Glock do this? Thanks for any help that might be available.
