Heeded. My thanks to all that took the time to post. You're right, there is no better way to get otherwise obscure information out. My question does not sound so dumb at this stage. - nvv

Thanks for the response, it's appreciated. The key issue is the protrusion, the length the FP sticks out of the bolt face with the FP fully forward. This dimension is easy enuff to correct, pull the pin and shorten/round off/polish the tip until you get to the .045' - .055" protrusion. Measure with a depth micrometer. The tip is accurately hemispherical, but just sticks out over double the amont I believe it should. Yes, I bought it, and if a long pin is all that's wrong I'll be very pleased. The recoil springs are STOUT and the cocking handle is a little bitty thing (the past owner tried to give me a piece of 1/2" dowel he called a 'chicken handle'!), and I'll probably fit a set of the EZ pull springs (which are expensive) and make a cocking handle that is longer and has external knurling. It's an interesting gun. Again, appreciate the response. - nvv

So I get tempted at the Melbourne gun show and buy an AO Worcester M1, semiauto. Looks pretty good, but when I performed the close inspection I should have done before, I noticed a firing pin protrusion that is just absurd, must be .120" at least. I'm not firing this, obviously. The question: I'm sure this is way out of spec; all the guns I've worked ended up at .050" protrusion or so. A 1/8" protrusion will surely rupture a primer. The most obvious (and probably oversimplified) approach IMHO is to adjust the firing pin length until I get that .050".....there's a protrusion gauge available somewhere for these but it's easy enough to measure. The FP is retained by a pin, but it appears to stop on the front of the pin itself and _not_ on the pin. The pin hole in the front of the bolt is large, about .115 to clear the .110" pin. That seems like a pretty large pin and hole, but then I'm more experienced in higher pressure applications where you'd not dare run such a monstrosity of a pin. Comments will be appreciated. - nvv
