So I have a mark 3 22/45 barrel and a mark 3 frame and just having a problem to get it to go together.

I just canít get the barrel pushed all the way on the frame?

The 22/45 barrel will go on a regular mark 3 frame?

you will have to remove a small amount of metal from the pocket under the receiver .
Go very slow and check you fit often . I use a small fine stone on my Dremel tool and using caution I have got some very nice fits on the grip frame to receiver.

This ^

The front locking lug is a bit smaller on the 22/45 frame. So once you make the receiver fit on a standard frame, you will probably need to add a shim to make it fit tight back on the 22/45 frame.

Start by taking just a little off the sharp edge. Sometimes that will be enough to allow the receiver to slide on snuggly. If not do the full monty as JStacy suggests.

Would one of you show me exactly where to grind? Maybe a pic?

Thanks Herman

Herman, before you start "grinding away" on anything I would suggest that you first use a soft hammer to gently try persuading the two components together after making doubly sure their alignment is spot on.

My Mark II pistol cannot be assembled/disassembled any other way, and I'm not going to just grind away at it's mating surfaces when Ruger themselves recommends the below procedures...

Directly from the Ruger Mark II Instruction Manual, entitled "Disassembly", page 20, step 5:

5. With the mainspring housing, bolt stop pin (as an assembly), and bolt
removed, a forward blow (with a plastic hammer) on the rear of the receiver
will disengage the barrel-receiver assembly from the grip frame
. No attempt
should be made to remove rivets or staked pins. Further disassembly should
be undertaken only by the factory.

Further on page 20, entitled "Assembly", step 3:

3. ...Push barrel rearward until it stops, with the rear end of receiver slightly over-hanging the rear end of the grip frame (see Figure 3B). If alignment cannot be achieved by hand pressure, strike the muzzle (front) of the barrel with a plastic or wood mallet only, being careful not to damage the muzzle.
