Hello
I have a 1907 .32acp pistol that is having a feeding problem. The gun has been used and needed some love and parts: safety catch, recoil spring, new magazines,sear, sear trip,some little springs, ejector. With the parts installed and a function test with dummy rds.
It fed and chambered and ejected fine. At the range fed it single Parvi rds with 6 in the magazine fired one and it jammed, the spent brass was sitting on the round in the mag making a nice jam. tried it again from 6 to 0 all jammed the same way with the spent round on the one below.

I am thinking it may be a magazine issue. is there a set of numbers on how far apart the mag lips should be to feed right?

or ideas please Thank you
