new guy here with a question or 3

[Clarkaim]

Here are some of the grips. pistol has an fxo mag, though it looks like it was made last week, it doesn't function in the pistol as well as an old beater 1920's era rusty mag I have of some sort I found out today. the bolt seems to catch on the rear of the mag body and not cycle the ammo. Mag switch and it's a fantastic shooting piece.

As to the grips, they are some sort of brown bakelite, looks like it might say made in germany on one of them. I guess it's aftermarket? any ideas?
