2 3/4" Chambers in a 1 frame 12 ga.

Joe:
Chances are you'll be fine. British proof minimum for 2 3/4 inch chambers is .140 just ahead of the forcing cone before extending the chamber. And Parkers generally run quite heavy in the barrel wall department. BTW... you need a wall thickness mic/gauge to check things.

Best, Kensal

We know of at least one ten gauge Parker that was made at the factory on a #1 frame and many #1 frame 12 gauges were chambered for 2 3/4" shells. Most #1 frame V Grade guns were late guns that left the factory with 2 3/4" chambers or nearly so. If you like it, buy it.

My 1/2 frame VH two barrel set has 2 3/4" chambers.

Joe;
PM me and maybe we can go over the gun as I can measure the BWT for you and give you my opinion if time allows.
