Glock 44 and mounting an RMR

I know it isn’t the ALG, but I use one of these on an M&P22 compact. It is a blast. I did need a shim to align POA to POI at 10 yards.

 
Good point. For the dove tail mount that I use, when running my suppressor, it has cycled everything so far (subs mostly out of it). It did have a stove pipe issue with subs when the can was removed. Mini mags and other high velocity rounds worked without issue without the can installed. The OP mentioned a suppressor, which is why I suggested this option.
