After 4 cartridge loads, the mags started loosing pressure EXCESSIVELY during the piercing process. Seems like the seal had compressed and did not retain it's sealing density. Have recently returned for exchange. Hopefully the exchanged will be positive.

Fits the M&P 40 very well, loads and unloads easily.

Seal does not retain sealing properties, thus loosing all pressure during and after piercing, seating.

Will this fit mp 40 no blowback

asked Clifford from USA

I can see in the comments that there has been problems with leakage. I experience the same problem with the original magazine and wonder if the problem with this replacement product now is solved.

asked Emil

Any tips on loading S&W Blowback M&P 40 BB Mag? my fingernails are nor strong enough to hold the little tab. its a real pain in the butt!

asked Wil

I use a pair of tweezers to pull the magazine tab down. If grabbed correctly, it is easy to move it into the locking slot. I have a really good stainless steel tweezer so it is very strong. I did this on the M9A1 Magazine but the picture here does not show a lock slot. I still think the tweezers will help. I am waiting on the M&P .40 to come into stock so I do not have that magazine yet.

Steve from USA

Why is just one of these so expensive? It's nearly half the price of the gun itself.....

asked Matt from USA

Any way to get extra hex head screw for holding in the co2 cylinder in this magizine?
