S-N-R: I once had a similar problem with an 1889 and, as I recall, ended up needing to replace worn-out or broken firing pin springs. The springs were supposed to push their pin back into the frame after ignition, but the originals no longer had the stuff to accomplish it. Now, an '89 has external hammers, and so there may be no comparison at all, but since they're both Remingtons, I thought I'd mention it until somebody who knows a lot more than me shows up ... which shouldn't take long at all.
