Ruger® Mark III™ 22/45™ .22 LR Rimfire Pistol with Bull Barrel
Ruger Mark III 22/45 evil features conquered!
The only complaint I’ve heard about the Ruger Mark III 22/45 is the evil pin that can be the problem field stripping and reassembling, so I did my homework.
I read the manual that comes with the gun, watched the videos on Ruger’s website and decided to take it apart and clean the factory gunk off of it.
The evil pin is actually the bolt stop that’s connected to the mainspring housing. Pulling out the mainspring housing was a snap but It took a couple good hits with a brass mallet and non marring drift punch to get the evil pin out so I could the finish disassembly. Putting it back together, the problem was first getting that pin back in and putting the connected mainspring housing back where it belonged. After about an hour I managed to get the pin back in but still couldn't get the mainspring housing back in.
Six Youtube video’s later, about 40 minutes worth, I learned the reassembly secrets, such as where the hammer need to be, how that evil pin actually goes back in and what part the magazine and trigger play in getting the mainspring housing back in, and managed to complete the reassembly.
I disassembled and assembled it another few times and took it apart a couple days later and put it back together with only a slight struggle.
I shot it last week for the first time. Great little pistol! The sights were off, a little low and to the left and the adjustable sights took care of zeroing it in. I shot up 200 rds of Federal Champion brass plated and 200 rounds of 35-40 year old Remington Mohawk lead bullets and had no feed or ejection problems. The magazine disconnect makes taking the magazine out a pain but after a few times it came out much smoother. If it becomes bothersome, the magazine disconnect can be removed, although it would probably void Ruger’s warranty.
I took the gun apart without needing a punch to get that pin out, cleaned it and easliy put it back together without incident. The more times I took it apart and put it back together, the easier that pin came out and went back in.
After I was finished I looked at the manual again. It actually has all the info needed to field strip and reassemble the gun. Unfortunately, it isn’t written in a manner in which the info jumped out at me, but it’s there. It would have gone a lot better had I’d noticed the step putting back the mainspring housing for the Mark III 22/45 is different than for the Mark III, where it says, “For 22/45 models, skip to 7A.”
I like puzzles so I didn't mind what it took to finally figure it out, hence the 5 star rating. I recommend this pistol but only if you have the patience and time needed to figure out how to take it apart and put it back together. Learning how is certainly worth the effort.

I bought this gun for a cheaper way to target practice than shooting my big handguns all the time. I try to shoot at least once a week and with this gun I don't have to take a loan out from the bank just to buy a box of shells. (and that makes mama happy) I've owned a Ruger 22 automatic years ago and loved it as a matter of fact I sold it to my brother-in-law and he's still shooting and loves it. This new gun shoots is so smooth and accurate I would hunt with it. I have fired aprox. 1000 rounds through it without any problems and expect to shoot lots more. It's a great little gun. The only issue I would have would be field stripping, it is a little rough putting it back together but after a few times (and some new words) it's not that bad. watch the vidio at the Ruger web site it will help.

would not buy again
bought ruger 22/45, shoots fantastic- however the dis-assembly and re-assembly of this gun would keep me from buying it again. i have many guns, all types, this is by far the most difficult gun to re-assemble i have ever seen. i do not believe this one will be in my gun safe long.........very disappointed. watched video's, read manual multiple times, possible defect? will be sending it back for repair and it will be gone. think about it before you buy it, i read many reviews stating these problems before i bought it- will listen closer to reviewers next time. i repeat- i would not buy again.

I used this gun to qualify as an NRA instructor. This is a very easy to use gun. My son also used it as part of BSAs Pilot program for a Merit Badge.
I now have four of this and use them as an NRA pistol instructor.
