Yes sir, actually more like 12,000 rounds now, I had a busy weekend.
I received my parts from S&W and decided I needed to wring it out after detail stripping and repairs were made.
I had 500 rounds of +P+ 115gr. Gold Dots, 1000 rounds of CCI Blazer, and a few boxes of Winchester "white box".
It ate the Blazer without a hiccup, but I kept getting early slide locks with the +P+ stuff, I finally realized that the additional recoil and my high thumbs grip caused my thumb to bump the slide stop lever, locking the slide back early.
An hour with the Dremel, file, and cold-blue, and I was back to the range. (I'm a perfectionist, had to make it look just right). I fired the rest of the +P+ and the Winchester with zero problems.
All is good in P99 land again.
