Is anyone aware of whether or not you can convert an M&P9 into .40 caliber?

 

[Jester]

nope, to much involved, end up being cheaper to buy one outright.

You "may" be able to just change out a barrel to switch from the 40 to the 357 sig...but the springs "may" need changing too. Nobody knows for sure...yet.



But the 9mm to 40 would definately be a MUCH bigger hassel...and with Bud's prices, I do believe it would be cheaper to buy a new pistol.

It works, and my friend did change springs. I'm jealous. He had the bbrl made.

Puffy,

Do you know who made the barrel for your friend?

Thanks,

Dan



Paynej21,

Too much hassel as the breach faces are different dimensions.
