I've only shot around 40 rounds and they functioned perfectly. I've heard sad stories concerning the mis-feeds with Promag. I guess you do get what you pay for.

Had a slight issue with the first Magazine, they sent me a replacement right away, at no charge. Would definitely buy from this business again.

ruger makes a good product, and you guys sell it at a better price than anyone else.

Great experience. Thanks

No surprise the mags work...they are factory mags. Delivery was nice and quick. Definitely coming back for more in the future
