I have a very nice 1919 20 Gauge on the way to me. The gentleman I purchased from noted a 2 3/4 she'll fit in it fine. But I am thinking it is a 2 1/2 in chambered gun and would like to confirm or test that when I receive it. Can anyone confirm standard chamber length and if a 2 3/4 she'll would fit? I can shoot either version of shell so more a matter of knowing for sure.
