Iver Johnson cylinder locks up - The Firearms Forum

I've got an Iver Johnson 3rd Model 32. When I fire it slowly, it functions just fine. When I fire it quickly, the cylinder will lock up. I then release the trigger, pull it slowly, and it fires again just fine. Does anybody have any idea what is going on?

Describe what you mean by 'lock up.'

Well, when I pull the trigger quickly, the trigger will stop about half-way back and the cylinder will not move while I have back pressure on the trigger. If I release the trigger, and then pull it slowly back again, it works fine. This only happens when I'm actually firing real ammo. When I put snapcaps in it, I can pull the trigger as quickly as I want, and it does not lock up.
