Hi - I'm new to the forum. I have taken apart my Model 31 shotgun, but I can't figure out how to get the slide, breechblock, or carrier out of the receiver. Can anyone explain how this is done? (P.S. - I got some disassembly instructions and a link for exploded view from this website, but it does not tell how to get the slide out.) Thank you in advance for any help you can give me!
