Same. I had one and it was a super inaccurate and frustrating.
Man, I forgot about that one till I read this, traded something for an HK USP .45 (not the tactical) back in '07, I had "great expectations", took it to the range and was sorely disappointed.
Spongy trigger and terrible accuracy, I traded it at my LGS at a loss.
So Rohrbaugh R9 (per my previous post) & HK USP, for me were my two biggest disappointments.
