Hi folks. So today was my third day at the range with my P2000 and I'm overall pretty satisfied. I was using a combination of Winchester Ranger .180gr ammo and Herter's TNJ .165gr rounds. Overall I fired 150 rounds with only one problem and I want to hope it was the ammo? I had had a jam on my first trip to the range but I attributed that to not cleaning the factory schmutz out of the slide and whatnot. This time everything was cleaned and lubed properly. The second trip was 200 rounds without a problem, and this trip was 150 rounds with one jam. I'm wondering if it was because of the combination of the two ammo types? I believe the Herter's ammo uses aluminum casings and I used those rounds second. Also, when I checked the round that it jammed on, I saw what looked to be a super tiny dent but it didn't look like enough to cause a problem. Maybe I'm nitpicking here but for a gun that I pay close to a grand for, I expect it to fire everything I feed it. Any ideas? I realize that I am very clearly a novice so any advice is good advice. Thanks again, guys.
