I went over to the local Police supply store to check some holsters for the MA1 series pistols. My new department requires High Gloss for class "A" uniform (long sleeve shirt and tie) used in formal occasions. (court, meetings, funerals etc). In Class B and Class C we can wear anything. I've been searching and searching for a nylon duty holster with a level II or better retention. Safariland makes a holster for the old Steyr M series, and it can be modified to fit the A1 (I have done this). After checking almost every holster in the store I found one that fits 99.9% perfect. It has a level II retention, and it also fits my new unfired unqualified M&P 9mm. The Uncle Mike's Pro 3 retention holster in size 28. It's labeled for the Smith & Wesson Sigma :? The H&K holster fit tight, but the grip was bad. Guess when I order my new nylon duty belt I'll order this holster.
