Need help with a ruger mark 3 target

[TKM]

Tear it down, takes less than five minutes to bare frame.

You may want to find some tight fitting pins to keep from enlarging the holes while media blasting.

I'd look into soda blasting. If you strip the frame down, since it's unserialized, you can bring it into any stripping company to do it. Soda blasting uses baking soda, so it's very gentle on the plastic below the paint.

I have access to a blast cabinet so I was thinking of bead blasting it but I was worried about getting any kind of media in the Trigger

Don't blast with ANY moving parts still in the frame.
Detail strip the frame of EVERY moving part before blasting.
You will need to get all the blast media out of it before you reassemble too.

Vapor blasting might be better than bead in this case.

I would probably use my hydro hone blast cabinet.

Don't be afraid to strip the frame bare, it is easy to reassemble.

Sarcasm font?
I took mine apart three years ago it’s still in pieces!

Some people are much more mechanically inclined than others.
I have no problem detail stripping and reassembling a Ruger 22/45 or MK series frame.
