I have one. Its a decent pistol. Its accurate, and reliable. The grip IS a wrap around rubber grip. Standard 1911 grips fit, but the screws are metric, so make sure you re-use them. It has a couple advantages over the GSG/Sig. Its tool less take down, and has a steel reinforcing pin in the slide stop notch. It also is a 12 shot, where the Sig/GSG is only 10. The Browning has terrible sights. There is no light between the front and rear when aiming, just a big black blob. FAIL.
One nice thing about the GSG/Sig is there are tons of aftermarket parts to customize your pistol. I have a GSG 922, and installed the +4 round follower, and +1 mag baseplate, making the mags hold 15 rounds. Its a nice little pistol with 15 +1 capacity.
Either way you go, Colt or GSG/Sig, you will be pleased, Im sure. I would pass on the Browning, because of the sights.
