I'd like to buy a BladeTech kydex holster for my fullsize P320 with suppressor height sights.
BladeTech's online customer service can't tell me that their holster works. Anyone here using a similar combination?

I went with a Ronin Concealment Holster from Gunfighter: https://gunfightersinc.com/ronin-owb/

They had lots of options to choose from including having a light on the RX. Retention was ok with the RX and light attached. Would have liked it to be a little more positive.

I bought a Red River Tactical OWB Kydex holster for my full size Sig P320 RX and am happy with it.

I purchased a Bladetech Classic OWB Holster last year for my P320 FS before I participated in two OpSpec courses. That pistol has Dawson standard height sights. The same holster also works fine for my P320 RX FS, which has the Romeo 1 and suppressor height sights. I will need to open-up the bottom of the holster a little bit, however, now that I have installed a threaded Silencerco barrel on the RX, as the barrel bottoms-out in the holster.

Earlier this year I purchased a Bladetech Signature Holster for my P320 X-Five, since I liked the Classic OWB so well.

I know it's not Bladetech but Safariland just came out with a retention holster that'll fit.

Thanks for the good info. If the BladeTech works for Merc50's P320 RX, it'll work for my setup. I like the holster - I already have one for a Smith M&P CORE 9.

Blade Techs are great for completion and intense classes.. Mine works fine on my P320 compact with the Romeo sight... but I did have to trim a small part to keep the front button on the Romeo from being pushed by it.

I have a Bladetech packaged for a FN.45T that I use for duty. I have had for about 3 years. The gun rattles in the holster, screws frequently come loose until I locktited the living shit out them. I wouldn't buy another but I cant find another retention holster for the .45T so it is what it is.
