To those who own a CZ and an M&P Give this a try next range trip it seems to function just fine. Magazines appear to be dimensionally similar and have a very close feeding angle. I would like to see more data and testing. I believe Mec Gar makes factory CZ Magazines and they should prove more reliable than any terrible Promags or questionable Magazine extensions.

CZP07 magazine is too small to fit in an M&P9 though. Should work in a 9C.

I'll buy a few next pay day as well, but I do not have an M&P9c to test the P07 magazines in. I'm thinking a cut down X grip could make things fit flush. I'd like to compare the height of an M&P9c with p07 magazines to a Glock 19.

19+1 seems like nice capacity for home defense/range use.

Let me know how this works out for you. If it proves 100% reliable a G19 sized M&P should be easy to do. (Was done before but it required cutting and welding magazines)

Looks short enough from the mag clip lock to the top end in length to give some problems but its good to see it runs fine. As the round count goes up and try'n a few different HP keep use in touch. Thanks
