When shooting Stingers in my Ruger 512, after the last round is fired in the magazine, the magazine ejects. Regular 22 ammo doesn't do this. Does anyone know why it does this? Is it bad?

I think a 512 is a MkII, right?

The top part of the gun can't undo the heel mag release - they have no connection. I'm thinking you never had the mag completely seated and the gun functioned anyway.

With the mag in all the way you shouldn't even be able to yank it out. Take a look at the release next time before you shoot.

512 is a MkII, right? 512 is AKA the .22/45, which has a mag release where God and JMB intended they be :D

Take it down and clean it,,,,pay particular attention to the inside of the grip area,,,crud can fall down into there and gum things up badly. Take apart the magazine(s) and scrub it (them) out also,,,pay particular attention to the front where the bullet rubs against the magazine. .22 ammuntion usually uses a "waxy" type lube that builds up on the front of the magazine.

If it still does it after it's properly cleaned and lubed,,,either:
- quit using Stingers in it - using them is pretty much a waste of money since you pay way more for what you get in return out of most pistols, for most uses.
- try loading either a standard velocity or a high velocity round on the bottom and 9 Stingers on top of it.

You also need the letters in front of the 512. The number's just the barrel length, the letters tell the frame design and coating. P designates 22/45, while MK designates MkII, a leading K means stainless while no leading letter means blued. A G on the end means Government model (laser targeted at the factory), a GC means Government Competition (drilled and tapped for a scope, and I assume also laser targeted).

For example, a (fictional) model KP4GC would be a stainless 22/45 with a 4 barrel that was drilled and tapped for scope mounts. A KMK678G would be a stainless 6 7/8" barrel on a MkII frame that was factory targeted.

Kharn, that's some GREAT info! Thanks!

Vanbeast:
No problem, I figured the code out after browsing the Ruger website while trying to decide what MkII I wanted (I eventually got a MK678G).

Great fun for cryptanalysts, I'm sure. Personally, I'd like to see guns called "the Cougar," "the Bear," "the Terminator," "the Liquor Store Commemorative," and so forth.

[vanbeast]

Liquor Store Commemorative!! I'd buy that!

I would still caution that the mag was not fully seated, but crud could cause that.

[Beav]

Its a KMK512.

The tension of the mag release was probably enough to hold the mag in the gun during most of the firing sequence. When the follower reached the top after the last round was fired the button on the side of the mag or the follower hit something and caused the mag to eject.

I cuss my ruger regularly but it says something if it will work without the mag fully seated. I just wish mine was reliable with the mag in any position.
