Hey guys, I just got a new M & P for duty. I needed holster for duty but the Safariland one is backordered and hard to come by. I did find out that the M & P will fit in a size 21 Uncle Mike's PRO-3 Triple Retention holster it made for Glock 17's and 22's. The internal retention device works also. It it a real nice fit, no slop or anything. Just wanted to let you other police guys know that this a good holster will work while you wait for you backordered ones. Uncle Mike's also make a similar light holster and it will fit that one too but that thing is just too damn big. It looks like a phone book hanging from your belt.
