Dry firing Ruger MK II. OK or Not?

[trickyasafox]

i've done hundreds of dry fires on my ruger mk II kmk512 with no ill effects. pistol is still pretty new though, maybe 5k through it?

The common wisdom seems to be that dry-firing a rimfire peens the firing pin where it contacts the edge of the chamber.

It also peens the breechface and eventually it will keep a round of ammunition from fully seating in the chamber, if it doesn't break your firing pin first. Use a snap cap, or a fired hull at the minimum, for dry fire.

Check out your manual page 16 under "Unload" #5. It is fine as long as the firing stop pin is in place.

I have the III Hunter and dry fire it all the time per their instructions.

The MkII has a firing pin stop the prevents the firing pin from hitting the edge of the chamber, it is OK to dry fire. (Same with the 10/22.)

The Ruger MK I does *not* have the firing pin block, so don't dry fire those if you can help it. In general it isn't a good idea with .22's as others have said, but the MK II does have a block built into it. I don't make a habit out of it anyway though.

Whatever gave you that idea? My MkI most certainly does have it. The "block" is simply a cross pin thru the bolt that retains the firing pin. The firing pin has a slot in it that the pin goes thru and the end of the slot stops the pin from striking the breechface.

The manual warns that dry firing without the cross pin will ruin the gun. Its possible to have the pin fall out while cleaning and if you fail to notice it ....

...then it's time to order the .22 Chamber Ironing Tool from Brownells for about 22 bucks.

The Mark II doesn't have a firing pin block. What it DOES have is a pin that goes through the bolt and firing pin that prevents it from hitting the chamber. It's perfectly OK to dry fire a Mark II or Mark III. This isn't true of other rimfires (like conversion kits for other calibers) but it's fine with a Ruger.

The proper term for part number A03500/KA03500 is "Firing Pin Stop".
