If you're going to mention retention for the love of God avoid Blackhawk. Unless you like shooting yourself.View attachment 37079
Safariland 578 GLS.
This is a level 1 retention holster. I bought it for my last security assignment I paid $51 for it plus shipping and it was worth every penny.
Here is a video description
Now that I'm retired I use this holster for hiking and I use it as a range holster because I can adjust it for either of my Glocks or my Smith & Wesson M&P9.
I was also very surprised how low of the profile this holster has. It has as low a profile as my Kramer holsters do and conceals just as well.
It's listed as a "retention" holster but it's really not any more retention than having a thumb break on the holster. If you grab the grip of the gun you unlock the retention feature.
Like I said I bought it for my last assignment, specifically because it's a paddle holster and I could take it on and off my belt without having to unbuckle my belt.
My last assignment was checking closed businesses and low-income housing in the middle of the night. If I interacted with three people in the course of the night it was a lot. I do not consider this to be a retention holster and I would never use it as a duty holster someplace where I was encountering a lot of people all the time.
