Storm Lake M&P 40/9 conversion barrel

[Schecter 81]

I was thinking of doing the same conversion on my M&P .40 Pro. The store where I bought it from said there might be a problem with FTE. Do you have to modify or replace the extractor when going from .40 down to 9mm?

I got my conversion barrel from CTCSUPPLIES. Fit great. It seemed to work fine with my hand loaded ammo in my .40 mags and fit an extra round. Would not slide lock on the last round though. The rounds are also very prone to popping out. With factory ammo, it missed and stovepiped every single round. Bought 9mm mags and it functions perfect. No need to change ejector.

No these are the 4.2" standard M&P barrels. Not for the Pro

Thanks.

Thanks.

I have run 500 rounds through my 9mm conversion storm lake barrel. Runs well with 9mm Mags, no failures. Very happy with it so far. Thanks CTC.

Can you bring in the 5" barrels for M&P40 Pro? The stormlake part number is SW-MPP-9MMC-501
