Storm Lake 40 to 9mm conversion kits

[gooseman]

I was looking at the S&W M&P 9mm but was rethinking the 40 because of this conversion kit I saw. I can have two calibers in one gun. Does anyone have experience with it? Also would this be considered something you wouldn't want to carry as far as alteration to the gun when the 9mm barrel is installed in a 40cal gun?
Thanks

I have one. There was a huge period of time a few years back where everyone was out of stock on these. When Midway sent me an email "in stock" alert, I immediatley ordered one. Unfortunately, in the haste to fill the shelves, Storm Lake's manufacturing process was a little off on the hoods the day they made mine. Caused the slide to stick when pulled back. Inside of slide would wedge against top of barrel hood. Notified Storm Lake but the customer rep. told me that I was simply required to fit the barrel as their website instructs. I fixed it myself by removing material from the top of the barrel hood. About two weeks late, I get an email from the same customer rep. telling me that the barrel was being recalled because they realized their milling machine had left too much material on the barrel hoods. No **** sherlock. (I hate when a manufacturer treats all customers like they are dummies. Too damn many people send guns and gun related products back to manufacturers for tiny irrelevant problems, causing everyone to be treated like the lowest common denominator. This is another rant I'll save for some other thread.) Apparently a number of complaints had been lodged since my first one. He told me I could send my barrel back to them and they'd rerun it through the mill. I told them I'd already fixed it myself so thanks for nothing.

Thing is fun to shoot at the range but you got be darn careful not to mix up your 9mm mags with your 40 mags. The S&W magazines are expensive too. I wouldn't ever carry it in the 9mm conversion. Just don't need too as I have other stock 9mm guns to carry when needed. I have done a trigger job on that gun too so it's got a nice range trigger but probably a little light for carry purposes.
