For those who never knew, the button on the follower is reversible.  I did one just to test, but since I use a hold-down collar to reload I don't really care which side the button is on.

Really, what the heck?  That's a lot of hate to find.  An unnoticed squib could be a cause?

I honestly have no idea what happened. The bore is clear, so if there was a squib it was blasted free. I'm waiting to hear from TANDEMKROSS whether or not their Essential Maintenance Kit for Ruger Mark Series pistols fits the Mark II or not. It says, Supported models: Ruger Mark III & 22/45, Ruger Mark IV & 22/45. Works with variants including LITE, Target, Hunter, Competition, and Tactical. But if you look for Mark II parts, there it is. I like the new extractor plunger and tools that come with the kit. This is so much better than factory stock parts. The video shows their KrossFire Bolt for Ruger Mark IV & 22/45, that they say works with Ruger Mark II, Mark II 22/45, Mark IV, and Mark IV 22/45. The kit has everything I want except the firing pin retaining pin. I still can't figure out how it got bent so bad.

I could tell by the slots that you could swap it, but didn't know if the mag would still fit in the gun. I just got a Thumb Saver mag loader from UniqueTek last Monday.

Thumb Saver Fits The Following .22 Magazines:

✓ Ruger Mark I/II/III/IV
✓ Ruger 22/45
✓ Browning Buck Mark & Challenger III
✓ Colt Woodsman & Huntsman
✓ High Standard Sport King, Supermatic & Target Models
✓ AMT Lightning
✓ S&W 22A, 22S and 22 Victory
✓ Beretta U22 Neos

Volquartsen has a Competition Bolt for Ruger MKII, MKIII, or MK IV, and they have Spare Parts for Competition Bolt for Ruger MKII, MKIII, or MK IV that also fit standard Ruger bolts. Since I needed a Firing Pin Stop Pin and an Extractor anyway, I decided to completely rebuild the bolt. I just ordered a Firing Pin, Firing Pin Spring, and Firing Pin Clip, Firing Pin Stop Pin, Exact Edge Extractor for MKII, MKIII, MK IV, and 10/22, Recoil Rod for MKII, MKIII, MK IV, and 22/45, Standard Recoil Spring for MKII, MKIII, MK IV, and 22/45, and Extractor Spring and Plunger.

You can get a Recoil Rod and Spring Kit with 3 weights of springs for $22.50, but it only costs $16 to buy a recoil rod and 1 spring, and all I need is the standard spring, not the heavy weight or reduced-power spring. They machine a chamfer or beveled edge onto the bottom edge of the exact edge extractor, improving feeding and reliability. It will eliminate any issues with the bottom edge of the extractor catching on the next round as it feeds up from the magazine. At first glance, it may look like a defect as it looks completely different than anything found on the factory part.
