I used my P-14 dual tone to go through Thunder Ranch DH1 5 day course last year. I never had a jam that wasn't operator error, and was accurate enough for what I was using it for. I later shout about a 2.5" group with it, at 15 yards. I have the origional mag that came with the gun, and the 2 extra high-caps from the cupons. One of the extras needed tweaking in the feed lip area, but they all work just fine now.
I put about 1000 rounds through it, and when I started the class I had put maybe 100 rounds through it.
What everyone posted before, about a full-up double stack .45 being heavy, is no joke. I had to prop my arms against my chest for the "ready" position by the 3rd day of classes.
Oh, a couple of notes that might not affect you or not, depending on your hand size. The later Para's have a much smaller grip than when they first came out. And, the grip safety and grip tang wore a hole in hand, when firing. However, I have very large hands, so this might not be a problem for you.
