Conversion barrel .22 TCM TO m&p 40

[NJM15]

Read the latest edition of American rifleman article
on the TCM .22 I know there is a barrel available for
Glocks does anyone know if one is available for the
M&P .40. I have KKM Sig .357 and 9mm barrels now

 

[Just another 22 shooter]

I'm pretty sure there is no 22 TCM conversion for the M&P.
If one ever happens, you will need to use your 9mm magazines in your 40. Fun gun in the 1911 platform; probably a good time in a
Glock, too.
