Good choice for le - Safariland Model 6377 ALS Belt Loop Glock Holster, Left Hand

I purchased this holster after my fed agency authorized the use of Level II security concealment holsters such as the Blackhawk SERPA line. Previously, pursuant to agency policy, we could only use holsters equipped with a thumbbreak. I selected this holster only because I found the placement of the security release to be more intuitive due to years of deploying and using thumbbreak-equipped holsters. As the firearms instructor for my local office, I wanted to also introduce to my fellow agents, also accustomed to thumbbreak holsters, to the world of security holsters together with a holster "manual-of-arms" similar to what they already had ingrained in their muscle memory. Although the SERPA holsters are easy to use, I have one for a Glock 20, my colleagues, unlike me, are not "gun people" and will not invest the time to draw their weapon from the holster to the level that they would need to be intuitive with the SERPAs.

I find the 6377 to be very fast to draw from. Hitting the "release button" is no problem whatsoever. While I believe no holster is 100% snatch proof, this one is excellent in that regard. Someone trained in the Lindell weapon retention method or similar officer safety tactics will appreciate an extra level of anti-gun grab security.

Now for the negative: this holster marred the top of my issue Glock 23 slide. No big deal as it's my work gun and if it keeps me safe then a gun grab, then marring of the slide be darned. I also use this on a agency approved, personally owned Glock 27 and have noted slight marring of that slide too...but very slight by comparison. Another negative, much bigger that a marred slide, is that the 6377 does not pull in the gun's "butt." As such, the gun's butt sticks out...a lot. Unfortunately, there is no way to correct that. As such, I find myself having to use very baggy shirts or jackets to adequately conceal the holster and gun. That is not good, but as long as you dress in a way to address that, you should be ok. In other words, look for shirts cut large or go one size up if you want conceal with a 6377.

All-in-all, this is an excellent holster. I took it with me to the FLETC firearms instructor course and found it every bit as "speedy" as my fellow feds using SERPAs, non-retention kydex and thumbbreak holsters....and much faster to draw from than the various Level III holsters in use by the uniform fed students.
Pros: Very fast to operate; non-obtrusive security feature; and very secure.
Cons: Slightly marred top of slide; "butt" of gun sticks out.
