I have one for my 1st-gen G17 that I like very much. It holds the weapon close to my body, is tight enough for firm holstering, the thumb break is easy to utilize, reholstering single-handed is a snap and the matching double-mag pouch is great as well.
All in all, one of the best $85 (for both) that I've ever spent...
