I've got an Ultra Carry II with tritium sights (although I presume you're getting yours from AimSurplus, right?). Using WWB I've had a couple FTFs in the first 100 rounds, both in the stock 7-rd Kimber mag and in a full-sized 8-rd Chip McCormick Shooting Star mag. I haven't had any problems with the handful of Golden Saber and Gold Dot rounds I've put through mine. It seems to shoot pretty accurately for its size, though.
I'm thinking that if I may look for some thinner grips, as the included ones are a little bulky for my taste. I tried Crimson Trace grips and found that I kept obscuring the laser. I'd also pay a premium for a non-checkered arched mainspring housing, but that seems to be dreaming the impossible dream.
