The 1922 Series Gallery Practice rifles were all .22 LR cal.
The Model of 1922 and Model of 1922M1 both came with headless cocking pieces. The M2 bolt had the knurled nut on it. It's purpose was not to control firing pin protrusion. It was intended to be finger tight. The most commonly seen Springfield .22 will have the M2 bolt installed. The near 20,000 or so that remained in govt. inventory were nearly all returned to SA or one of the arsenals to have the M2 bolts installed. My apology for chasing rabbits on this thread but the bolt configuration topic slipped in.
John, After wasting 30 minutes trying to send you a PM I am adding to my post that I have some 1922M1 magazines. email me if you want one.
