I have been having problems with extraction from my 1927 (more info on the pistol here).
I did not have a problem shooting Winchester from Wal-Mart for target shooting, and Golden Sabers for around the house. Recently I got some S&B and UMC, and they are not ejecting about 1 in 3 rounds. The Golden Sabers still work well, but not the other 2.
I know some pistols like some ammo better than others, but wanted to see if maybe some chamber polishing would help. So I took it apart and first checked to see how tight the chamber was with fired casings from each type, and fresh rounds of each type. I think my chamber seems to large (new rounds seem loose).
I took out a set of calipers and made some measurements:
S&B:
.484" Fired Casing widest part
.479" Fired Casing at the opening
.473" Unfired Casing Widest part
.470" Unfired Casing at the opening
.046" Rim thickness
Golden Sabers:
.481" Fired Casing widest part
.477" Fired Casing at the opening
.473" Unfired Casing Widest part
.470" Unfired Casing at the opening
.041" Rim Thickness
.483" inside wall to wall of the rear of the chamber. That seems loose to me.... Do I need a new barrel? (it is quite old).
