PRO MAG - M&P 40 .40S&W, 15RD

Magazine works great. Have had no jams or problems with chambering a round. Ejects just as easy as the OME mags I got with My M&P 40. Would be nice to have the round size on the mag and the S&W Logo but not sure if that might go against copyright laws.

Hi, Lets talk about these Pro-mag clips for the M&P40. The magazine have a rough blue finish, and have sharp edges, and have no trademarks on the steel, only the numbers that indicate the ammo loaded (Which is a good thing, because if you change the magazine floor plates, it may seems like a factory one) Anyhow, the magazine steel tube and the plastic follower are remarkable, because both have a higher inclination angle than the factory one which gives to the bullet the space enough to reach the ramp and get in the chamber flawlessly instead of hitting the feeding ramp and jam the slide. These issue was found on the first gen M&P's (2007- 2009). Where the feeding ramp was shorter; and the factory magazines did not give the right angle. (The later versions of the M&P came with the feeding ramp extended correcting the problem.) Now the real problem of this magazine; is the spring, which is not so durable like the factory ones. Meaning that it may won't last reliable and strong for much time. In my particular case what i was needing were the steel case, because I already had the springs (those of a Glock 22) . In summary, if you want these magazine for self defense i strongly recommend you to change the springs. If it is for target practice, they are good enough for the price.

These mags honestly should be a no star as they do not perform at all like they are supposed toyou might be wondering why I gave them a two star well. These mags are wonderful for trainingtraining to reload and clear jams. I bought these mags on a spur of the moment and wish I hadnt, Always stick to factory magazines. These mags wouldnt feed half the time and even had rounds flipping straight up.

Bought two for my SD40VE and they just don't work. They have a problem with follower tilt. I changed out the followers with S&W followers and took a Dremel to the leading edge of the magazine to give a bit more clearance and still didn't help. I just threw them in the trash.

Rough edges, came already scratched up and dented in a way that doesn't match normal use, stovepipes roughly 30% of the rounds, and only holds 14 rounds, not 15.
