Where do stripper clips fit in an M1? Or even an M1 carbine?
M1 Garands take en bloc eight-round clips, not stripper clips just in case you’re ever going to get one.
I was waiting for the technical argument to come in.
M1 carbine has variable size magazines. The "hold open" on empty relies on the follower in the magazine. My rifle had no mags at purchase. Hunting around town, I found 5 rd and 10 rd mags. One with the "hold open" follower. If the bolt face has a fitment for a stripper clip, you can push them in from the top. My SKS has a bolt like that. The magazine is fixed. Most of the laws are written around the capacity of removable magazines that can be quickly exchanged.
