In 2023 I got my hands on a pile of Tulster holsters and they’re great. Previously we reviewed the Tulster Profile holster and really had a great experience. One of the models we were sent was the Oath, and it’s a serious contender! We carried a Glock 43 in the Oath for several months and here’s the verdict.
The Oath

After our great experience with the Profile, we started using the Oath. The Oath builds on the design of the Profile in a way, and instead of offering up a plastic mono-clip, there’s a spring steel MOD4 U belt clip. The MOD4 U clip allows for the holster to be “tuckable” and suitable for appendix carry.

In addition to the spring steel clip is a wing, to push the holster and firearm closer to the wearer’s body.
The unit is constructed of heavy duty Kydex. At the end of the holster by the muzzle, the Kydex does wrap a little around the business side of the firearm. Like the Profile, the Oath is open at the muzzle end.
Oath holsters are ambidextrous and only require the user to swap over the hardware. Because these are ambidextrous in design, there are full length sweat guards on both sides of the Oath.
Our experiences

I prefer the Profile over the Oath. That’s not to say that the Oath is not good. Again, the Oath is tuckable, and the Profile is not. The monoclip is what attracts me to the Profile, whereas the Oath will stay in place better due to its clip design. I prefer being able to easily remove my holster/firearm combination, over having the design elements of the Oath.

The spring steel U clips are super aggressive. I was not in love with them. That’s okay because Tulster has plastic clips or leather straps. You can get those options from Tulster and change out the spring steel ones if you find them to not work well for your applications.
As noted, I carried my Glock 43 for several months in the Oath and did not have any issues. It was as comfortable as a hard plastic holster can be. With the wing, and U clip, the unit did not migrate much at all. This is a great option if you’re going to be in business or business casual attire that requires a shirt tuck.
The quick and dirty

Pluses: Affordable. Quality materials and construction. Ambidextrous. Can swap out the clip hardware. Can tuck your shirt in when using it.
Minuses: I was not a fan of the included spring steel clip.
Overall, I can recommend the Tulster Oath holster. While it’s not my favorite, I was able to carry without an issue using it. After giving it some more time, the holster may grow on me more. If you’re in the market for a holster like this, it’ll probably meet your needs without question.
