Lots of pros a con. - Safariland 6378 ALS Paddle Holster - STX FDE Brown, Right Hand 6378-419-551

Great for competition, duty or tactical use. Unlike the Serpa it locks on to the ejection port and not the trigger guard and is a better, smoother draw even under stress. I now have 3 and my favorite is the glock 17 with surefire x300. Last thing this holster does work with the thumb safety models.
Pros: Durable, easy to draw, positive lock, protects guns finish.
Cons: To big for concealed carry work.
