Like the title says I have a Smith & Wesson M&P .40 I know you can swap in a 9mm barrel and magazine and I have a M&P9. Its awesome!

Question I have: Can I get a longer barrel from say LINK I know that the barrel would stick out 3/4 of an inch but will it fit?

Anyone know?

Thanks in advance

Take your barrel out, if it's outside diameter is straight for the last inch or two then you probablly can. If it's like the 3rd gen metal guns with a bulge near the muzzle that fits a bushing in the slide then you would need some machine work to a longer barrel and a new bushing made. Probably be cheaper to just buy another gun. Now if the make a threaded barrel for your gun then it would be longer and suite your needs.

Why would you want to do this? The large point of having a longer barrel is to have a longer sight radius. If you have a longer barrel but the same length slide, the sight radius is the same so no improvement is found.
