the ONLY difference between the 9mm luger case and the 9x23 winchester case is 3 millimeters in length.
i emailed armscor maker of rock islands .22TCM asking about dropping in a barrel for 9x23 win.
all i got was a talking front office head who stated ..."it is impossible to convert the .22tcm to shoot .38 super." (notice she said .38 super.) stating that "her" gunsmith advises against try as the bolt face is not wide enough to accept a .38 super on it or behind the extractor....which indeed it's not (if i was talking about .38 super;.....i'm not tho. i clarified my inquiry by stating NOT .38 SUPER!...9x23 winchester!.......She emailed back ..."my gunsmith said NO!"
they sell the gun with 2 barrels and slide springs ...one each for .22TCM and the other for 9mm Luger
the magazines are the same for both cartridges (they indeed are magazines for .38 super and fit the gun perfectly .(incidentally wilson combat magazines in .40 smith & wesson also fit perfectly inside the .22 TCM ...only the feed lips are profiled differently.)
now then .... i've read that .38 acp...9mm largo...9x23 win.....38 super...38 super comp...and .38 Todd garret brass for the most part will fit inside a .38 super barrel....with the width of the rim being the only disqualifying factor. ruling out the .38 super as it is a semi rimmed case.
however the 9x23 win is nearly exact within 2 thousandths in diameter ...same rim profile ...same cutaway for the extractor groove in the brass ....the only difference is the 3 millimeter longer length.
has anyone else done this?
are there any problems to trying this?
