I would've guessed yes, by 1/4". Good to know.

No it only has the ejection port opened slightly and ejector lengthened .

Ok then, how about my 870 super mag? That's probably been lengthened right?

Only a few first year 1950 ports in 870 and I have not run into one yet. Rest are all the same except 3 1/2

My old 870 (#500###) has a port opening measuring 3 inches and the pump action moves a total of 3 and 7/8 inches

OK so what are you saying. There is a difference??? Between a 3" and a 2 3/4 870 and that serial number is not old IMO LOL
