A great resource is Rimfirecentral.com. Not to discount many of the fine folks here at THR..
I have a couple of MKII's. Have had four in all. Some of my friends have MKII's. I don't know that there's a typo in the manual at all. But you can always go to Ruger.com to download the latest print.
All you need is a paper clip for a take down tool. Don't worry about rapping the barrel off the frame with a block of wood, (I use a leather mallot, holding the frame in my left hand, hitting the rear of the reciever with mallot with my right hand. Some people just rapp the same on the gun bench with the muzzle pointed up. I lay a nice fluffy towel on the bench in case I hit too hard and make the barrel fall off quicker than I can catch it. In time, you'll learn how hard to smack it. In time it may just push off with some brute force by hand.). But you don't normally need to compelely dissassemble any more often than a thousand rounds. (or twice that) -Depending on what dirty ammo you're running. As for reassembly, the key is knowing where the hammer spur is, where it's supposed to be, how to get it there, when you're reinstalling the mainspring housing. It's just like anything, a little practice goes a long way. The easiest way to learn this is to get with a buddy that has a MKII. He'll show you how. Then you'll laugh, because it's so easy. Not like some of the reassembly horror stories we've all heard.
I've tried some of the most expensive ammo through my MKII's and have found that CCI copper plated, WinX, WinT22 function quite admirably. And, the Win's are up there with some of the top shelf target ammo when it comes to accuracy. Mine and a buddy's MKII will print one ragged hole at 25yds from Ransom rest with them. No need to buy the really espensive stuff, but the middle of the road are good. I have had more misfires, not misfeeds with RWS than any other brand. I even shot some Federal match for a while, while accurate, the misfires affected my Bullseye scores. Back to the WinX I went.
As for cleaning. Full dissassembly is not required for just clearing lead from the barrel. The lands aren't huge, so leading isn't a big issue, but you do need to clean them once in a while. Pull the main spring housing, pull the bolt. Clean from the breach with a .22 rod and patches with your favorite lead solvent. You'll need a 10" rod to do it this way. Not the standard short pistol rod.
If you're shooting the CCI's, you'll still have to clean out copper fowling.
When I clean:
- Pull the grips
- Remove mainspring housing
- Remove bolt
- Clean bolt and springs and firing pin
- Remove barrel/reciever from lower frame
- Spray out trigger and moving components in frame with Gunscrubber.
- Lube frame internal moving components with Breakfree
- Spray out and brush clean reciever
- Clean bore with patches/brush
- Spray out reciever again
- Reassemble
- Go shooting!
Once you fall in love with this little plinker that's inexpensive to shoot, there are several modifications available. While the Browning Buckmark may have a better trigger out of the box, the Ruger has more options available for trigger, sights, grips, internal springs, hammer and sear, firing pins, extended releases for magazine and bolt stop, compensators (not to mention that magazines are cheaper, but don't buy the plastic ones).
WWW.Volquartsen.com is a good source. Clark Custom Guns has stuff for them and I'll plug Trapper Springs as the first modification I make to a MKII.
I'll call these the 1911's of the Rimfire shooters, since there's so much you can do to make them function as part of your hand. Accurate enough for Bullseye. Quick enough for Speed Steel. Reliable as hell.
