I've always wished I could have a dropped/offset Safariland ALS holster with a Blade Tech tek-lok. Today I noticed that I had a spare tek-lok and a Safariland mid ride UBL from an old duty holster. I also had a brand new Safariland 7TS "concealment" ALS holster (The one that comes with the paddle and the close in belt attachment) that my wife got me as a gift a while back. Seeing all three in the same space got my wheels to turning. Before I knew it, I had drilled holes and attached the tek-lok to the UBL. It worked like a champ, and gave lots of extra functionality to the holster. So, why bother with a mod like this?
1. The UBL is super strong but is meant for Police duty belts that are 2" to 2 1/2" wide. This mod allows you to use a 1.5" or 1.75" EDC belt. This also allows attaching the holster to a CR Speed type competition belt as well if retention is desired, which is becoming popular in 3-Gun.
2. I can now choose between clipping the holster on with the tek-lok only, or running the belt through both the UBL and the tek-lok for extra stability. The clip on function is nice at the range for switching out a concealment holster with this holster since I wear a belt with a cobra buckle.
3. For owners of the US Grunt Gear war belts, you could do this mod to attach a Safarland holster to that belt without using a G-Code molle adapter. I've never owned one of those buy I've eyeballed them longingly on their website before.
I put the holster on in both configurations with my EDC cobra belt and I was extremely happy with how stable it was during the draw, even with just the tek-lok holding it on. With the new tek-lok's retention tab I don't see it coming off unexpectedly.

Thats a good idea. How do you like the ALS holster? I just ordered one.

It's my favorite retention holster by far. I think the new 7TS material is also a huge improvement over the older suede-lined design. I also have one of the newer GLS holsters, but I think it's inferior to the ALS and will probably sell it. I may be biased to the ALS just because it was my first duty holster when I was a LEO.

You magnificent bastard!!!! And I mean that in the nicest possible way  Great idea to overcome the shifting on a smaller belt.  Thanks for posting this.  Off to the work bench....

Now just add QLS to all your holsters and bases and you've really got a great modular solution.

Nice mod you did. Which size Tek-Loc plate did you use? I was looking at some to do this myself and saw that there a couple of different sizes.
