Model 577 GLS™ Pro-Fit™ Holster (with 1.5" - 1.75" belt width belt loop) is rated 4.6 out of 5 by 31.
Rated 4 out of 5 by from Good Retention and a faster draw than others... I bought two GLS holsters to use in 3-Gun competition, one for an HK VP9 and another for a Sig P226 SAO. The HK fit perfectly after a little adjustment and setup was easy. Safariland does not make one of these officially for the Sig P226 with a rail but with a little adjustment and a slight modification it works great. Retention of both pistols is good with no looseness or noise and drawing the pistol is fast as the retention device is released when you take a proper grip of the pistol. These provide a great alternative to the ALS system where retention is needed and for me is a faster draw as I do not have to train my thumb to release the pistol from the holster. My draw did not have to change as with the ALS or other systems that use the index finger to release the lock.

Rated 3 out of 5 by from Good for multi guns, not great for retention Bought this holster for two reasons. First, I like the idea of having an intuitive retention design that does not slow the draw but does provide some level of protection against gun grabbers. I'm not a fan of the finger button on the Serpa design. Second, I was intrigued by the fact that one holster would fit handguns from numerous manufacturers. To the second point, the adjustable design does seems to work well with the guns I've tested it with. However, the retention design seems poorly executed and is actually TOO intuitive. It seems to provide adequate retention in the event the wearer falls to the ground but when I asked multiple people to "try and take my [practice] gun" from behind, the retention lock released every time simply because of how the grabber's hand naturally grips the gun. Preventing a grab from the front might be more effective, but from the rear it is not an effective retention design. So depending on what type of retention you are concerned with, this holster may or may not meet your needs.

Rated 5 out of 5 by from ONE OF THE BEST HOLSTERS OUT THERE! I purchased this holster for my Ruger SR for use in 3 gun competition. I attached it to my Safariland gun belt with the QLS system so I could quickly change it out with my M & P Pro 9mm. I love this holster! The grip locking system is very natural and is pretty easy to get used to with a little practice. Took me about 30 minutes of drawing to get the grip and release just right. At the range it worked slick as a trick! Very satisfied and will probably get a LH model for my wife.

Rated 5 out of 5 by from Great holster for your money! Bought it for my Walther P99, and it fit great with a little adjusting. The GLS system works perfectly, and I'd recommend it to those not looking to drop a ton of money on a concealed holster. Definitely worth every dollar!

Rated 5 out of 5 by from Great Holster. Went though a 4 day defensive handgun class with this holster and it worked perfectly. I do not recommend the drop rig with this holster because it gets in the way of a good grip on the gun. With the holster on the belt as it is made, the grip is much more stable and quicker.

Rated 4 out of 5 by from Works for both my guns I bought this holster primarily for my Sig P229 40 s&w Enhanced Elite. It does fit with the included spacer. Sometimes it is difficult to reholster due to the decocker. With my Springfield XD I experienced none of these problems. With both of the guns, they locked in but could move up and down in the holster about 1/2 an inch. Side to side and front to back there is no play.

Rated 5 out of 5 by from Safariland Holster Model 577 I purchased this holster for competition carry of my Glock 17. This is my second holster from Safariland. Both this and my previous holster fit my weapons perfectly. The trigger guard release allows for quick but safe draws from the holster. I plan to purchase another holster in the near future from Safariland for my next competition pistol.

Rated 5 out of 5 by from Great Holster After using it a while now, I find the retention is fine. Although I think I read advertising that it won't mar the finish of the firearm, it does somewhat effect the finish a little. Pistol is a slight bit loose (forward and back flop) even tightening the internal shoe adjustment slightly less than too tight for draw, it moves a little. Otherwise, I like it for what I bought it for - Works great.
