As I've posted earlier, I was having a hard time with constant FTEs since getting my slide replaced. During my first outing with my updated pup, I was only able to shoot a few rounds of 124 grain Speer Gold Dots without any issues. All other types of ammo resulted in multiple FTEs and quite a few light primer strikes that required a second shot. Needless to say, I was really disappointed.
Well, I got a chance to hit the range again last night after receiving my ammo shipment and things seem to be much better. The session began with a few FTEs with Speer Lawman and American Eagle FMJ but seemed to get better as the night progressed. After about 50 rounds with intermittent issues, I was able to reliably shoot over 60 rounds of mixed Speer & Federal FMJ, 135 grain Federal Hydro Shok and both 124 grain and 115 grain Gold Dots. I'm beginning to think that the new slide and internals just needed to be broken in like some 1911s. However, I did find that I had to tighten my grip screws every 3 to 4 magazines and my pup doesn't care for Hornady Critical Defense. Looks like I'll have to reapply some loctite tonight and feed the rest of my CD to my HK USP.
Thankfully, I think I can avoid sending it back in for any more service. Throughout everything, I've never had any failures with either weight in Gold Dots, which I will continue to carry. I'm a happy camper now!
PS: sorry for the lengthy post.
