Questions on the MK I .....



Log in to see fewer ads
.....is the take down procedure for the MK I basically the same as that of the MK II ? Also I have seen some pics of MK I's with no warning labels on the barrel. What year did Ruger start stamping the barrels with the warning label ?
It seems that MK I magazines are not all that easy to come by ...will MK II mags work in a MK I ?

Take down procedure is basically the same. My understanding is that MKII magazines will work in a MKI, but you have to disassemble the magazine and change the button over to the other side.

Mark II mags will work in any Mark I/RST. You MAY need to switch the button if the pistol is an earlier one with the A54 grip frame.

...and in some case you may have to reduce the diameter of the follower button.

My 1978 RST4 and RST6 do not have the warning on the receiver. I have seen 1979 RST's with the warning on the receiver.

1978 (my MkI T678 has the warning stamp)

All post 1972 MkIs-YES (will work As IS)! Pre-1972 MkI's (w/A54 original grip screw patterns) need the MkII mag follower button switched to the mag's right side! Additionally, changing out the mag release to This will allow MkII mags to operate much better than the OEM release!

Almost.

Trigger pivot is fixed by an e-clip on the RST/Mark I.

No bolt release on the RST/Mark I.

The safety is the bolt hold open on the MKI. While holding the bolt back in itís fully retracted position move the safety into its safe position to hold the bolt open. To close the bolt pull back on the bolt and move the safety into the fire position and the bolt will close. At least the MKI target works that way.

I know.

The context of my comment was differences in disassembly/reassembly.

the way I read the message was field strip, if the question is for a full take down, there are minor differences. E clip on the trigger pivot, added LRHO to the Mk 2.
thanks to those corrections...

I know I'll be executed for this but........I've never even attempted to field strip my MKII. I just flush it out with polymer safe gun scrubber, get to what I can with a toothbrush, and blow it out with air. My Buckmark Plus is sooooo much easier to clean!!!
