Extended Magazine Releases for Ruger Mk I, II, III, and 22/45

I installed some after market grips on my Ruger MK II target pistol and it exacerbated an already known problem with the magazine release. Along with just being "rough" on the thumb before the grip addition, the factory magazine release contains a spring that has a tendency to slip off the factory release and bind between the release and the frame of the pistol making the already unpleasant action of releasing a magazine that much more difficult. The new grips also made getting to the release more difficult as well. This aftermarket extended release is one of several versions available in the market that really makes a difference with these Ruger pistols! After installing this new extended release, it solved the problem with the binding spring AND made the action of releasing the magazine soooo much more easy and pleasant with the new grips! Solved both problems and is well worth the money! Highly recommended!

I installed the Mk I extended magazine release on my MK I A100 frame pistol and it was a 5 minute perfect drop in part. It works perfectly with no modification. I'll never be able to go back to one of the old factory catches after using this one, it is so much easier I may even use it in competitions that require a reload now. I saw the other review that mentions it not working in an older A100 frame but it worked perfectly in my A100 frame but it was made about 1981.

I ordered this extended magazine release for a mark 1 pistol. However it does not fit seamlessly into the mark 1. If you purchase it plan on having to file it down and work on it just to use it on the mark 1. It may fit perfect for mark 2 pistols but didn't work for me on mark 1. - EABCO Note: Majestic Arms has recently discovered that Pre-1961 A100 pistols do NOT fit this Mk I extended mag release. If you have a pre-1961 pistol, it will have A100 printed under the left grip panel. We have revised our description to note this incompatibility.

Easy installation. Makes for an easy to reach magazine release lever. Soooo much faster than the factory release.

I own a Mark I that I use for steel competitions and plinking. It has been passed down to me and I shot about 500-800 a week if I am able to. The European style magazine release has always been a pain. Thankfully, the Majestic Arms extended mag release has been a life and finger saver to say the least. Times have been cut down in reloading and I have fallen even more in love with the MK1.

Best Ever!!!!!!!!!!

Works great, easy to install.

This is a great device but I had to have a friend put it in as my hands are arthritic.

have owned my Ruger Mark one for over thirty years, have always had trouble with the factory release. wish I had bought one sooner.

This extension makes it easier to drop the mag without losing your grip. It is also easy to install.

makes mag changes so much easier. installs easy and looks good

Took a little final fitting with a file and now works like a charm.

First of all, it functions perfectly. However, when they call it extended they aren't kidding. It really sticks out--about twice as far as it needs to. The problem is in holstering your gun, especially with a leather holster. As you do so you can accidentally engage the magazine release. Then there is a possibility of losing the magazine in brush or while seated, or at least having it fall out of the gun when you draw it. A nylon holster gives a little more and the potential problem is not as great, but still there nonetheless.
