I just happened to come across 4 brothers while I was searching for a mag holder. Not only did they save me time from having to drive far but everyone at the shop was very helpful and absolutely amazing. They made my holder right there while I waited and not only is it a perfect fit with expert quality but also comfortable. I will most definitely be returning anytime I need anything.
Perfect fit!
As usual...all good! Retention adjustment is easy...holds mags great for my monthly shot factor competition.
Have an Echelon build going so I'll be circling back soon for a new holster.

Quality materials and fast turnaround time. Very happy with purchase.
I’ve had a few different magazine holsters, and they were nice but the Four Brothers mag carrier is fantastic. The retention is controllable so I get the exact amount of force needed to remove the magazines as I’d like.
Plus, they are incredibly well made and put together. They look great and carry well. I’ve used them at the range and are easy to draw from but I feel comfortable moving quickly with them on.
