I have a Ruger MK III/22-45 problem

Post by rdstrain49 » Tue Oct 16, 2012 10:29 pm

My problem is these things just keep following me home. Another 22/45 followed me home today. It is used, has been shot a lot and never maintained. The sear had a chip in it, the hammer notch was worn badly. It took about an hour just cleaning it, getting ready to start working on it. I did salvage the hammer, then recut and salvaged the sear. Did away with the magazine safety. Now it's ready for a trip to the range (pasture) tomorrow. The trigger breaks like glass at 3 1/4 lbs. I'd like it to be 3 1/2 lbs, but given the condition of what I had to work with, I'll take it the way it is.

My biggest complaint about the MK III series is that they are too easy to work on and it doesn't take much time to fix them up. Now what am I supposed to do tomorrow?

Did you take pictures of the before and after? If so post them, would love to see the condition before hand. Also welcome to the Forum. Bullseye and everyone else here is very helpful.

Welcome to Guntalk-Online!

Sounds as if you had a good project going there. Another great thing about these pistols are a steady flow of replacement parts from multiple manufacturers. Hopefully the hammer and sear will function smoothly on your refurbished pistol, that isn't often the case when these are re-cut without the proper stoning jigs even the smallest changes in the component geometry can have huge effects on these pistols. Another project you may wish to undertake later is installing replaceable grips on that molded frame. I find the early non-replaceable grip frame a little too slender for my hand size and a set of new grips makes the gun more manageable for me.

When you test fire it make sure you only put 2 round in the mag to make sure it will not go full auto. The add another round and test again till your up to a full mag. It sounds like you will be installing a VQ hammer/sear in the near future.

Some people are scared to detail strip these guns. If they only knew how easy it's actually is with the proper guide....... Thanks to Bullseye :wink:

Bullseye; I agree 100%, anyone who thinks they can do major cuts on a hammer or sear by "feel" is just kidding them self. My only concern is that I may have had to cut so deep that I may have gone past the hardening, time will tell. The grip does feel a bit small, but I'm going to give it a try before doing anything.

blue; Where's your sense of adventure, the last time I had a pistol go full auto was with a 1911 (hand cut sear & hammer) about 40 years ago. I still remember that as being a religious experience. Caution shall be the watchword.

1911 full auto happens faster than one can even say,"SH....!"

Somewhere I still have the 1911 sear that did that to me, just as a reminder. Funny thing is, even after all those years I don't need any reminder.

You are correct, the experience embosses itself into one's brain.

Just my opinion, but this is the only way to work a sear & hammer.

I agree the Power Custom Series 1 stoning fixture is what I use for most firearm hammers and sears. With the right adapter installed it is easy to control the depth and angle of the cut with the stones. I use a Series 2 fixture for 10/22 trigger parts.

Range test this morning. Function was perfect, trigger not perfect but very very good. Didn't even have to dink around with the sights. Shoots to point of aim at 50 yds. 25 yd rapid fire averaged mid to high 90's. Since the intended purpose of this weapon is that of a field gun, I think it's ready.

Here is the finished project.
