These are the Ruger brand for the 22/45 Mark IV and they work as expected. I clean them after 500 rounds and have never had a problem with them. You may need to use a lite sandpaper on the edges where the external head pin for the spring resides, but that is it. Check them regularly, clean them regularly and they will last. I have several that have over 4000 rounds use and they are still working superbly.

Say folks these mag are not as good as i thought they would be I put rounds in mags at range only to have them pop out when i rack the bolt . The last two or three stay in but i think these mags need some kind of adjustment. It is not worth it to me for all the shipping costs and time to deal with them . I have been told to get the ss mags as they work better. I will try to get these to work better if i can. Now if you would like to send me some ss mags in lu of these it would really make my day. But we no thats not going to happen.Have a Blessed day. Bill

These mags are very well built and reasonably priced. Check out the TandemKross video on tuning these mags. Smoothing out the rough spots from manufacturing aid in reliably feeding and already reliable gun. If when you pull down on the loading assist it feels a little rough or crunchy, the tuning will smooth that out completely.

Received these magazines in a timely manner. They came as advertised in the original packaging and fit ion my 22/45 without a problem. Ruger products are always of goo quality and I have several products by them including the PC carbine, AR 556 and a Mark IV 22/45 Lite. All of them are perfect in operation.

OEM magazines the same as the ones that the factory sent with the gun. They work great and are worth using over the aftermarket varieties that are available.
