Not for a Smith and Wesson Sigma
If you were buying these magazines for a Smith and Wesson Sigma they fit but they do not cycle rounds so My advice to you is to stay away from them if you’re purchasing them for a sigma

Great Products
So many aftermarket magazines do not feed properly. The ones I purchased from Cheaper than Dirt feed perfectly. I took them to the range and shot 50 rounds through each magazine and every round in bothmagazines feed perfectly.

Not so much
Honestly, I don't like either magazine. I bought two in case they worked really well. When pulling back the slide and releasing, doesn't grab the round, simply gets stuck. I don't have that with the originals.However, these were bought for a SD40VE, because many sites stated that it would work. Apparently not.Oh well.

Uh, Nah. 2nd bad mag in 6 years.
Item: MAG-428-060 This number is for the Pro-Mag for M&P 40. The SD & M&P by Pro-Mag are exactly the same mag body. Only difference is the floor plate. This magazine locked in just slightly lower than a factory magazine. It would not feed unless I tapped floor plate, then it would raise up just enough to feed the round, After ejecting it still would not feed the next 40 S&W flat nose bullet. When I put the floor plate from the M&P Pro-Mag on this mag and put in my M&P 40 it worked. It will however feed 9mm ammo into my 9mm conversion barrel just fine. I will keep it and use for 9mm shooting only. Have used various Pro-Mags in last several years. 2012 my wifes Ruger P-95 did not like Pro-Mag and now this. Still a very good average. 3 stars because I will use, but not for intended caliber.
