I can see (and even know of) 1100s converted to full auto. But converting a PUMP to full auto? That's right up there with converting a revolver to full auto. Might be doable, but surely seems stupid.

I think the poster might've been thinking of the Ithaca M37. I'm aware of at least one such conversion back in the day. As to full auto revolvers; this was once purportedly done using a single action center fire as the basis. Rear portion of the cylinder was trimmed - much like the 45acp & half moon clip conversion done on Webley .455s, thus providing a greater gap between the frame's recoil plate and rear face of the cylinder. Firing pin was lengthened accordingly. The falling hammer and pin would move the cartridge forward, the cartridge would discharge as it came to a full stop against the cylinder's rear face, cartridge (probably with a punctured primer) would move aft upon discharge, recocking the hammer, and if the trigger was still being held back the cycle would repeat. Have to agree with the above statement that such a conversion would be really stupid. Can't remember where I read about the actual modification.
