A few years back I inherited an old Mark 1 22 pistol. I believe it's approaching 40 years new. It's pretty well used and in need of some updating. First off, I need a new bolt or bolt assembly as well as grips. I'm not into spending a ton on a $100 gun, but I would like to update this and have my daughter shoot it. Any suggestions on where I can by parts for this pistol? BTW: even without the updating, the gun shoots very sweet.
Why do you think it needs a new bolt? I have seen many many old Rugers and never seen one that needed a bolt replacement. Usually they can just be cleaned up.
The grips are easily replaced, but you will need to know which grip style it uses (pre or post 71), use the chart here, and let me know which year it was made. http://www.ruger.com/Firearms/PS-SNH-PI-MarkI.html
The metal on the bolt is worn thru from repeated cycling to the extent that the internal spring is exposed. I've shot it that way with no trouble, but its due. I'll try to get some pics tonight. mine is a 1973 model 11-
BTW: the trigger appear to be faux metal...plastic made to look like metal. Was that standard in 1973. Makes the gun look cheap.

Just out of curiosity, which internal spring has been exposed due to wear? The long recoil spring on the top of the bolt is normally exposed its full length.
The recoil spring is exposed as designed. However, on the right side of the bolt the metal is worn and a spring below the surface of the bolt is partially exposed. I will break it down and see what I find. (I'll also post a pic). The gun has a lot of holster wear and and the sights are dinged up a bit, but the bolt is the only obvious issue...besides the cheap looking trigger. It is still a shooter, though. The barrel looks great, too be honest.
I assume this is up-to-date, however the code at the bottom of the page makes me think it is from 1999. But it is a place to start. Contact details are omitted, so it may be a chore to contact the correct people to place an order.
Wow, that's the extractor plunger spring. Never seen a gun with that spring visible like that. It's not supposed to be visible, as you guessed.
I would think that perhaps there would be corresponding wear in the mating surface inside the receiver. Is there appreciable lateral play between the bolt and the receiver . . . that is, is the bolt "sloppy" inside the receiver?
If there isn't a lot of wear, I'd guess the hole for the spring was drilled improperly.

For the trigger, you'll almost HAVE to get an aftermarket replacement.....unless somebody on here has made a conversion already and has their old trigger handy. I haven't seen a plastic trigger, and have to wonder if the aluminum trigger is just showing places where the anodizing is worn off.
