This Magazine carrier is getting phased out. We are replacing it with more specific carriers built for the Smith and Wesson M&P 10MM and the Sig Sauer P320 XTEN 10MM Magazines.
Smith & Wesson M&P 10MM OWB Magazine Carrier
Sig Sauer P320-XTEN Magazine Carrier
Our Outside Waistband 10MM and 45 ACP Double Stack Single Magazine Holster is vacuum formed with a precision machined mold designed from CAD models of the actual pistol magazines. Each holster is formed, trimmed and folded in house.
Our single magazine pouch is designed to fit double stack 10MM and 45 ACP pistol magazines from Sig Sauer, Glock, FN, Walther, Ruger, Smith & Wesson and others.
The magazine retention is adjustable by turning the set screw of the Magazine Retention Device with an 1/8" Allen wrench.

Built well, I just wasn’t crazy about the clip design.
I purchased this holster for my M&P 10mm magazines. I got the mag pouches and it works flawlessly with Glock 20 mags as well as Para Ordnance p14-45 mags. The unique retention system and attention to detail makes this an excellent mag holder.
Get it! Won’t be sorry.
Best Shield X holster. Slim, good retention, and comfortable. Worth the price. Shipped fast. All positives.
This holster has exceeded every expectation I had. Quality materials. Amazing fit and finish. No complaints at all so far and I carried this holster everyday for the last 2 months. Have already ordered the IWB version amd will be ordering more holsters.
Thus holster has a lot great first impressions. Unfortunately I had the send my staccato back in to HQ for them to fix an issue I can’t wait to get my gun back to use this holster more.
Fits perfectly!
Amazing holster. I’m very glad with this product. Thank you and see you soon in your shop for a next buy.
