Mark III Mags difficult to insert



Log in to see fewer ads
Just got a new to me Mark III Hunter. The mags hang up when half way inserted, requiring one to depress the mag release to get the mag inserted. Is this normal? If it is, it STINKS! Is there any way to fix it? Will it get better in time? The gun has very low round count. Sorry if this has been answered, I did a search but turned up nothing. Maybe I’m searching using the wrong terminology (I’m new to this.). Thank you.

Have another Mark III owner insert your mags in your gun. What one person thinks is excessive force is normal resistance to others.

This issue is pretty common (but not "normal") on mark 3s.

You might consider adding a bottom-side taper to the release. Here's a vid that shows the idea. He went a bit more aggressive than I think he needed to, but it worked okay for him.

Thank you. I was thinking about beveling the bottom of the mag release. I’ll try what’s detailed in the video. My mags absolutely will not insert without pressing the mag release, regardless of how hard you whack the bottom of the mag.

If you push the bottom of the mag to the right, it should insert without pushing the release button in. If it doesn't, the button retaining screw may not be fully seated. Check the frame threads for a burr from the tapping process, then fully tighten the screw to the frame. Between the 2, you should be fixed up.

I had the same problem when I owned my Mark III stainless Hunter 5.5" barrel. Mags would hang up if you didn't slightly depress the magazine release button upon insertion. It drove me nuts. At the time the Mark III was still fairly new so not much info on the web about the problem. Ultimately I ended up selling it because I didn't like the grip angle and ended up with a 22/45 which I like much better. Like others have said there is a fix by beveling the bottom of the magazine release a bit more so it slides out of the way during insertion.

Well, After having the Ruger a few days and handling it often, I see that there’s also a certain “touch” to inserting them smoothly. I’m getting the hang of it.

My issue with the Mark III is failure to eject magazines. I always expect to press the mag release and for the empty magazine to drop.

Nope, you have to pull every magazine out by hand.

That's typically the mag safety holding up the mag. Get a MKII style bushing and replace the MKIII bushing and mag safety with it. The mags will "shoot out" like you expect.

I don't recommend using any of the aftermarket MKIII bushings. They all add a lot of creep to the trigger.

I found that on some of the MkIII magazines the catch notch in the magazine body will often (especially on newer magazines) have a burr on the edges of the notch. Hitting it with the stone one or twice removes the burr. You should not see much bright metal is you remova JUST the burr.
