Howdy all.Got a 1927A1 commando deluxe,all steel and 5 30 round sticks.1 is a kahr mag,single hole and 4 modified "oval" sticks,(I didn't do them).ALL will charge a round into the chamber on a pull and release from the bolt,fire and the second round will jam.The round gets stuck almost to the chamber,kinda like a stove pipe issue, with the bolt face bottom pinning it to the ramp.Having to use a block of wood on the charging handle to free it from the death grip.It leaves a " crescent mark" on the case from the bottom of the bolt slightly below the rim of the case mouth and a "rub" mark on the FMJ nose as if it was really trying to run up the ramp.There is also a long "scratch" I am guessing from the ejector along the whole length of the case in which case I suspect the bullet isn't getting past it unscathed.
The mags lock in nice,well like they are supposed to.Measured them from top of hole to lip of mag.They seem to be all over the place as far as consistency.The kahr mag mic's out at about 0.975",the modified are somewhere around 0.980 to 1.080". Any ideas as to what I should be looking for or at.The ramp looks a little rough,but the bolt and everything else is smooth as pie.I am not a rookie around weapons so I can do the work needed,just never worked on a tommy before,every weapon has it's issues and peculiarities.thanks all for any insight to start with.
