Bought a Strongarm at the Goodwill today for $7. Came with only five darts, and the cylinder doesn't turn after firing, but that's no bother!

Tomorrow or this weekend, I'm gonna crack it open and try and fix it up. Anybody got any advice beforehand, though?

E: Okay, checked the cylinder. it doesn't always turn after firing. Slamfiring seems to increase the likelihood, but not be enough.
