Thank you for the replies.
I've seen the USP mags in the 2000sk (I think). I believe the bottom of the mag extends past the hand grip (Which is to be expected.)
This feature would not benefit me when carrying concealed as I seem to have an issue with the bottom of the mag printing and/or catching on my shirt. At the range, the mag interchangability would definitly be a bonus.
I can not seem to find a P2000sk in a V1. Something I should have mentioned in my original post was that I am not willing to give up my manual safety. Others don't have a problem with the LEM trig, but it comes down to personal preferance.
Reading the reviews, both pistols are excellent. I don't think I can go wrong with either one. I'm leaning towards the USPC in a .45 but I must admit that I have yet to actually handle a 2000sk. The closest place for me to do this is 100 mi away. I think a road trip is in order this weekend.
(And no, I can't afford both.)
Thanks again.
