Preface: This is a small "review" of the conversion barrel I bought for my M&P40. I am only writing this, because if I saw this before I ordered the barrel I would have made my decision a lot sooner.
I am the proud owner of an M&P 40 (yes PROUD, I love the gun). With the ammo supply issues not getting any better I decided to look into a conversion barrel so I could shoot 9mm and save a few bucks during my range visits. At the time, buying a Beretta 92FS just was not in the cards so I needed a cheaper way to get a reliable 9mm. I figured the conversion barrel was the best solution, this way I don't have to learn a new trigger or anything, just continue practicing with the M&P but with 9mm in lieu of the .40S&W. So I purchased a Stormlake 9mm conversion barrel a little over 1.5 months ago along with 2-M&P9 Full size mags from GT Distributors ($25/ea+ S&H, not too shabby). I know why they were only $25 a piece for the mags though, you have to be PATIENT. I am going on two months and only got one of the two I ordered. Anyway, I digress. So, in the comfort of my home I field stripped the M&P40, set the .40S&W aside and slipped the 9mm conversion barell in it's place. Not a single problem at this point. The M&P40 and M&P9 use the same spring, so no need to change that just switch out the barrels. Put my .40S&W mags aside (I mean I buried them in my bag so I would not confuse the two because they look VERY similar). Put my 40 barrel into a soft glasses case and loaded my 9mm mag. Then I took it to the range and tossed in my laser boresighter (just in case). Everything was lined up fine, so I went ahead and removed the laser and slid the 9mm mag right into my M&P40. I put 100 rounds down the barrel with no issues. I have since purchased a few more 9mm mags (full price $40/ea ) because I can't wait for that second mag from GTDist. and have not looked back since. The gun looks pretty sharp too in my opinion because its polished stainless whereas the stock .40 is black to match the gun. I still plan to keep the M&P40 chambered in .40S&W when at home or when CCW because I like .40 as a defensive round, but now I can keep shooting the M&P40 and save on ammo but shooting the 9mm.
So, in summation here are some numbers to ponder:
M&P40 New: +/- $510 (think they are a little more now)
Stormlake 9mm Conversion Barrel: +/- $160 (+ S&H) (expect about 1month for the barrel)
M&P9 Mags (GT Dist.): $25/ea (+ S&H) (expect 1 month each barrel not running concurrently, 2 mags=2months)
Total to have an M&P40 and a M&P9 in one gun: $720 (plus tax & S&H)
Or, cost of an M&P40 new and a M&P new (2 guns): $1020 (+tax)
So, for the money, I say it is worth it to be able to chamber .40 and 9mm in the same gun. I will still get a Beretta 92FS in the future, but for now, I like having the one gun be capable to shoot both size rounds. I would recommend the Stormlake Barrel to anyone interested. I hope someone out there finds this helpful! I know I would have, and I wouldn't have hesitated so long if I found something like this beforehand.
Happy Shooting!
