I bought 3 of these magazines
They are suppose to hold 10 rounds. 2 of the 3 magazines will only hold 9 rounds. I tried several different brands of ammo, but only 1 of the mags will hold the reputed 10 rounds and it was difficult getting the last round into it. Now if it takes Promag magazines time to break in to hold the stated amount of rounds, they should advertise this. Over the years I have learned that Promag magazines are notorious for this. It is a hit or miss with them, this time was a miss. They do hold the 9 rounds fine and will feed my S&W M&P40 Compact, but I have not been out to shoot with them yet. Promag, either put an * with a disclaimer about a needed breaking in period OR make your mags to hold the advertised amount of rounds! Factory magazines that come with the gun do not have this issue and neither does Mec-Gar magazines. Pros: Fits & feeds fine Cons: 66% will hold 1 rd less than advertised

No it will not.
Will this work with a Smith & Wesson model 187020?
