Like everybody else with a MA-1 I've been looking for a good holster for it. I looked around at a couple of different sites and didn't find much. I talked to the guys at High Noon and they offered to alter the M holster to fit the MA-1 since they have the mold but it was going to be very expensive ($120) and take at least 12 weeks just to make it let alone ship it. I really liked their product but was not crazy about this. That's when I found AKJ on the list and to my pleasant surprise they are STOCKING their MA-1 holster, I got mine in three weeks. Granted the color was limited to brown and only in ambidextrous. But for $66 shipped I was sold. They have a very unique design for their IWB. The way they keep the mouth open is by folding over the spine and stiching it to itself and some very good wet forming. It keeps it open enough that one handed reholstering is no problem. The hole under the threaded rivet for the rear belt loop is so you can adjust the angle to your preference. By unscrewing the rivet you can also change it from right to left handed. There is extra material that extends past the muzzle to help break up the pattern of the muzzle to keep from printing. All in all I am very pleased with this holster and the workmanship is very very good. In my opinion if you are looking for a IWB for your MA-1 or any other gun for that matter you aren't going to go wrong ordering this one.
