I have a generic .22 auto holster from Blackhawk on backorder, but today I went browsing through my box-o-holsters looking for a temporary solution.
With the adjustable sight in place, a Fobus BR-2 paddle hoster fits it "like it's got eyes", as my uncles used to say. It also fits okay with the rail and Fastfire, but the rail pries it open a bit at the top; okay for the range maybe, but not quite secure enough for field carry. The BR-2 is desiged to carry M9s, CZ75s, and the like. A little trimming of the rail forward of where the FF sits should fix that.
The other good one I found that works is an old, American made Uncle Mike's shoulder hoster meant for large SAs like the 7 1/2" Bisley I used to carry in it. It fits well, even with the rail and FF, and the strap goes over the trigger guard properly. The only potential problem is that the mag release is right against the fabric and might let go if bumped. The holster fits so well, I'm going to figure out a fix for that.
