Don't know about the model 17 Rem., but my old Ith. model 37 would sure slam-fire. I never did it intentionally, but sometimes it would fire the 3rd shot without me being ready. Often killed ducks that way after I'd missed'em twice.

I've never tried to slam-fire my model 12 Win or the Rem 17 and don't recall it ever happening with them. The Ithaca was bought new in the early '60s, possibly built earlier...Geo
