I would not buy
I bought 2 mags only fit 15 rds each of 40 smith & wesson which after did not fit into the 226 very well, a base plate replacement would be the only way to resolve it, was disappointed when they claim Quality.

Great mag for the price
Man up and skip the speed loader, go slow and be consistent with every round when loading and it'll feed just fine, will be ordering more soon after a few more range days to check it's reliability

I have two and will buy more!
Be a man and use your thumbs not a speed loader, the spring is hella tight so leave it loaded and the spring will loosen up to fit 30rnds. These mags are great quality! Make sure to pack the mag after every 10 rnds

Jams if not loaded slowly and carefully
This is the third ProMag I've purchased recently (20rnd Sig 226 .40, 20rnd Walther PPQ .40 and 18rnd Sig SP2022 9mm). The 20rnd mags for the 226 and PPQ work ok but get jammed up if I load them with my speed loader too quickly. The 18rnd mag for the Sig 2022 9mm jams up after (10) rounds every time I try loading it. The springs in the ProMags seem to be very touchy. I'm going to stick with the Mec-Gar mags. I have about a dozen or so Mec-Gar for multiple handguns and they've never failed on me. Mec-Gar are more expensive than ProMag but cheaper than the factory mags.

All three I bought had th
All three I bought had the same problem. The follower tries to feed the bullets upwards at a 15-20 degree angle and jams against the top of the barrel every 2-3 shots. Poor quality followers is my guess, or the spring is not properly manufactured. Also, you can fit 18 in the mag snugly, but 19 and the last round rattles, not that it matters, since they are not reliable. This may work for a 9mm but for .40, do not buy!!!

Bought two of them. First
Bought two of them. First one got 20 rounds in it no problem. The second one, I am pretty sure the bone will break in the thumb before the 20th round goes in. So I guess I got a 20rd mag and a 19rd mag. Still ok for $20 a piece.
