This IWB is amazing, well done and really low profile as it should be! The mono block has a nice grip at the waist making it great for an easy draw, I love it, I’ll be purchasing the mag carrier to go with it soon!

Briana Hyppolite Every time I need a holster for a firearm (IWB), I buy one from here. Can’t beat 4Bros Holsters. I have ordered other holsters that just don’t stay secured when drawing and dry firing. These simple holsters never fail. 4Bros will always have my business.

Michael Salvato Four brothers have become my go to Holster because of the ability to adjust height and cant. The ability to do micro adjustments, lets me carry and conceal perfectly with every firearm. My old favorite Holster was great, but certain Guns if I went one up or one down, it was either too high or too low. Four brothers fixed that.
