This is a high quality product. Great fit and stable over a XL T-shirt Because of it's modularity, it can be configured to fit almost any holster and hand gun you want to run. I plan on buying another one soon to fit my "End of Days Gun" a compensated HK USP 45 ELITE.

First chest holster
100% satisfied with this item. Easy to assemble and it feels great to wear. I use this for my side arm while hunting, I wear it while walking my land, and I also wear it while running machines. Ive even worn it while fishing. Great holster mount that doesnt get in the way.

I love the style but whises the shoulder straps were longer, so that I can set it at the height I want.

Outstanding quality once again!
Hello,
This is my second holster from 4Bros, and once again, they nailed it. The build quality, retention, and attention to detail are spot on. It fits the firearm like a glove, rides comfortably all day, and conceals exceptionally well.
Consistent craftsmanship and reliable gear — couldn't ask for better. 5/5 stars, hands down
It does exactly what it says! It’s a good wedge. My only complaint is that it is a little on the stiffer side, but without the stiffness it wouldn’t can’t the holster inward properly. Overall satisfying.
I purchased the Smith & Wesson M&P Shield X & TLR-7 Sub IWB Holster from 4 Brothers, and I couldn’t be happier with the product or the customer service.
The holster was well made, with solid construction and quality workmanship. After using it, I found that the slide extended slightly beyond the sweat guard and was digging into my side. I contacted 4 Brothers, and their customer service was top-notch. They stood behind their product and, under warranty, sent me a replacement holster with a slight modification to address the issue.
The new holster is perfect! I really appreciate that 4 Brothers listened to my concern, took it seriously, and went the extra mile to make sure I was satisfied.
It’s refreshing to deal with a company that stands behind its products and genuinely cares about its customers. I would absolutely recommend 4 Brothers to anyone looking for a quality holster backed by exceptional customer service.
