    Ruger Mark IV Bolt Issue?

    Didn't they years ago warn people in the owners manual to be sure the FPSP did not drop out while being reassembled?

    Two Piece Bolts

    I bought a SS Mk2 Target a couple months ago that had the two-piece bolt. It is in my extra parts stash now. I replaced it with a Mk4 SS bolt. It is the second SS Mk2 I have bought that has had the two-piece bolt.

    Finally tightened the loose receiver on my Mark I

    It goes into the squarish hole under the barrel where the frame lug goes into and you move the barrel back to seat it on the grip frame.

    Finally tightened the loose receiver on my Mark I

    I have used an aluminum soda can shim in one of my older Mark pistols too. Works great. When I got it, someone had already "dimpled" the cutout in the barrel, but it wasn't working anymore. I was reluctant to use the squeeze the barrel method, so tried a shim, it worked.

    Lost 10-22

    I have not lost a gun yet, but have looked high and low for a few now and then. But....I did lose a Garmin Dashcam, and looked for it for a year, Then thought it was stolen from the car during the night I guess and felt stupid. Then one day, I open up the top of a parts box I had just bought...

    Mark IV: (or any Mk) How long do extractors typically last?

    I have a few Mark pistols, and I always make sure the factory extractor is de-burred, and I break the edges. And male sure it works smoothly in the extractor slot. I have found at least one slot that had burrs that needed attention too. When working the extractor in the slot by hand, if one...

    Two piece bolt

    Thanks for posting that pic of all the various bolt styles. I recently bought a Mk2 SS with the two-piece bolt and swapped in a one piece like you have pictured. Of course I would have been unaware if not for you posting about this two-piece bolt here and elsewhere.

    Mark Ejector Rivet

    I saw a long time ago where a man made an anvil to fit in the receiver to fit umder the rivet. Make your own anvil to fit if you can. Tight fit under the rivet, so it can be peened from the outside. Made from a piece of straight bar stock. Also, someone makes a screw in type as well, think I...

    25 yard off hand. Not great but a surprise contender

    To the OP, you have have excellent eyesight to hit the target a 75 feet. Are those targets designed to be used at that distance?

    Mark IV 22/45 in stainless?

    They might as they have in the past. The first 22/45s had a model in the lineup with a SS Barrel. I have one. It is the Heavy Taper Barrel style. I got it at a gun show in Lewiston Maine a couple years ago.

    Thanks SGW Gunsmith and Ruger forum!

    Glad you brought your pistol back into use again. I use SRWs tips on mag tuning too, including the polishing of the mag recoil spring guide. Some are really rough, others are polished already, maybe different batches from the mag maker? I dunno.

    Extractor caused burr in chamber

    Good that they replaced the barrel. I did not see any alternative see any alternative except to keep on shooting it, and hope for the best. The extractor is designed to contact the area further inside the extractor slot to keep this from happening. Your extractor must have been different somehow.

    KP512C?

    I just bought a 1992 22/45 with the heavy taper barrel in stainless, and the bolt is blue with the Ruger eagle on it. I thought it was a KP512, but after reading this, I dunno. I have researched both text and photos by Google and saw another pistol identical to the one I have, and it is...

    My recall took 10 days from the day I mailed it, til the day I got it back. (WBR Target)

    Mark II Serial number

    Thank you for the follow-up to the original post. Interesting that you came up with 1989, when you thought it was a 91, and others a 90. All good. And great information.
