sw m&p barrel change?

[Adamz04]

Are the smith and wesson M&P series pistols compatable for barrel changes like the glocks are? such as 40 to 357

 

[Triton20]

I think the only M&P that you can do that with is the 40 to 9mm.

I believe the 40 to 357sig is also a go. the mag followers say 40/357. I plan on a 357sig barrels for both my m&p40 full size and compact.

You won't have to buy new mags if you go to the .357 barrel from .40 either.

I was curious because i always see and hear people talking about the barrel swaps on glocks which makes them more appealing. I wonder if there are other makes that you can do that with?

Most of the people who swap barrels with the m&p usually get the conversion barrels which I believe is only made by storm lake at the moment(there may be others, but I don't remember at the moment). The issue you'd get from just buying a 9mm barrel and dropping it into a .40 is that there're are difference in the geometry of the outside dimensions which can effect lockup and timing and barrel/slide wear. Although I have heard of people doing that without issues, there's still a chance of damaging the m&p. I bought the storm lake conversion .40-9mm and still had some issues with the 9mm not sitting right and the firing pin missing the primer and hitting the rim. Not sure what caused it though, haven't used it since. I guess I need to try it out again and see. Those are just my oberservations and YMMV.

Good luck with whatever you chose!

Ive heard of people swapping out .40 and .357 barrels on Sigs w/o issue but never tried on any of mine.

Im thinking about getting a .357 barrel for my .40 P226.

Defenatively adds some attractiveness to an M&P40. I hope to pick one up in the next few months and get a 9mm barrel for it.

you can buy conversion barrels but make sure you get the proper extractor and mag if you go too high or too low

I was thinking that my extractor was the issue, I've got the 9mm mags, but as I said, the round wouldn't sit right and the firing pin would strike the rim or just outside the primer. I may get the APEX FRE and try it again. Plus it may help the occasional erratic ejecting of the shell casings...

I haven't tried swapping barrels yet...just bought my M&P 9 Pro this week. But if you look on Midways website, they have original S&W barrels for $68.00. They are sold out rite now...but the comments say they work great.
