I just purchased the M&P .40. One of the details I like about the M&P line is the after market support for the gun. I know there are several conversion options out there. .40 to 9mm and .40 to .357sig. I am just curious if anyone has tried these and how it worked out for them.
Works great, I have convert for 357 and 9mm, Smith and Wesson drop in conversion barrels from Brownells.com or midway. With the 9mm you need 9mm mags botach.com $23.00 free shipping
