I just picked up a Bul Ultralight with a compact grip after catching the 2011 bug from picking up a Staccato C2 in February (it was my first 2011). I really like the gun, and I've already ordered a Viper with the full size grip. Bul's 15-round compact grip is actually 5mm shorter than STI's compact grip, but since this is an "Officer" size 2011 I felt that it needed to be even shorter... so... dremel, drill press, belt sander, various files, determination, and an afternoon bored at home = chopped grip and shortened magazines for a flush fit. The Bul 2011 compact magazines are about the only thing I don't like about this handgun (based on the RIA/Para double stack mags), because the magazine base plates are a pain to remove and reattach compared to the full-size mags. However, that attachment method makes it relatively easy to shorten the magazine body and drill new holes for the base plate mounting tabs. The base plates are also unnecessarily long at the front lip, so I shortened that front lip for better aesthetics. I cut 0.300" off the magazine body and the grip for a flush fit when the magazine is inserted. The shortened magazines now only hold 14 rounds, but I believe the gun looks better and conceals better. In addition to chopping the grip and beveling the inside of the newly cut magazine opening, I also rounded off the sharp edges on each side of the bottom of the trigger guard to make it more comfortable when gripping the gun.
