Glock 44 backpack or trail gun
 

I bought this thing because it fits my old G19 holsters. (don't have a G19 anymore) and wanted a 22 pistol for a long time. now I find myself carrying it more then my S&W model 60. ow so light and accurate 16.40 oz don't even feel it on the belt. If you like Glock this pistol is a winner.
