Hello. I have a Safariland 6378RDS ALS holster with the oem belt loop attachment. I use a 1.5 inch belt so looking for a 1.75 inch attachment at most.

I am thinking about going to a mid ride UBL with thigh strap.

Is this what I need or something else?
- I prefer the UBL not be cantable but looks like that's not an option
- I don't need QD and want to keep the holster as close to by body as possible.

I’ve got 3 of the Trex Arms leg straps that I run on low ride UBLs. No issues there.

Yes, but get it on ebay to save some money

The CUBL is correct. I much prefer the Trex Arms thigh strap. If you have more than one holster throw the QLS stuff in your basket as well.

Agree with these dudes, the T-Rex strap is legit. Consider a True North drop as well. It provides a much more solid rig.

These part numbers came from Google AI but they look correct:

The standard, non-cantable Safariland UBL is not manufactured in a dedicated 1.75-inch width version. Safariland only molds the rigid, non-cantable Model 6070UBL (Mid-Ride) and Model 6075UBL (Low-Ride) in two standard base widths:

2-inch belts (Part Number: 6070UBL-2-2)
2.25-inch belts (Part Number: 6070UBL-2-25 or 6070UBL-2)

If you strictly need a 1.75-inch UBL that won't slide around on your belt, you can use the Cantable Version (CUBL). Safariland explicitly designed the adjustable CUBL to accommodate 1.75-inch tactical belts. Even though it is built to be adjustable, you can securely lock it straight up and down (zero-degree cant) during installation.


I locked mine straight up-and-down and it has held securely.
I also utilize their QLS system.

You don’t need a thigh strap on a mid-ride, and I wouldn’t recommend one even if it were easy to add.
It’s the Low Ride where you really get into optional thigh straps. I still wouldn’t recommend one though. I dislike them.

I actually prefer a high ride unless you need it lower to clear body armor.

Mid ride was my preference as a patrolman because that was low enough to clear my armor without really being low enough to hinder me from staying seated in a vehicle for most of a 12-hour shift.

For SWAT duties I prefer a low ride because it clears even the bulkiest Level IV armor no matter how you’re moving around physically.

This is great. Thanks.

Does this work well when running? I'm looking for minimal flop

Listen to this man right here.  100% concur.  

And yes, works fantastic running.

True north has a few newer variations of the MHA as well, take a look at their website.  May find a variant that fits your needs a little better.

Yes, as long as your belt loop size matches your belt’s width, it’ll work great while running and while drawing.

Sometimes people want a strap to keep the bottom of their holster from pivoting outboard while they draw, but those people are drawing incorrectly. If they drew straight up they’d never experience that issue.

+1 for the True North MHA (would order it anywhere else than GBRS though), the UBLs are just not comfortable.




I also prefer to run the leg strap as low as possible, through a flexible hanger (dunno who makes them anymore though):




The T Rex Arms straps are nice:
