22/45 Mods

So one came home with me today. 22/45 Target, blued with 5.5" bull barrel.

I would like to do a couple of things right off the top and I was wondering if anyone can post links to mods for removing the LCI, Mag safety disconnect, and any other basics that will help. I here someone makes an LCI replacement piece that is non functional to keep the factory look.

I went a couple rounds with this one already today. I wanted to clean it and get familiar with the procedure. After cleaning it and spending a frustrating hour or so I got it down. I also watched a quick video on how to make the mag "slingshot" out. All it was is to flip the spring off the lever that contacts the mag and then it goes under the lever and holds it up. Sure enough it worked, the mag flies right out. Problem is, the hammer wont cock. I guess that spring does more than that. I figured that had to be the problem so I put it back and it works fine again.

Any help on the mods would be great!

You take the upper off and give it a few taps on the top with a rubber mallet.
The little pin holding the LCI will come right out.

To remove the magazine disconnect, you will need to remove the hammer pin, and pull those set of internals out. Be watchful of the disconnector. If you let that fly up, you stand the risk of losing the trigger plunger and spring. After the internals are removed you can lock the trigger disconnecter down the sear

You will need to take the hammer off from the hammer bushing to get to the magazine disconnect and spring. You will need to either add a few resized washers to take up the space the disconnect left open, or replace the whole bushing with with one from a MKII pistol.

You have several options there.
You can get the one from Majestic Arms, or one from Volquartsen, or buy the Clark MKII bushing. Many people swear by the Clark, though it is almost triple the price of the other two.

Pop the bushing back into the hammer, reset the trigger disconnector, and reinstall in back into the gun.

i would also adding a VQ sear and trigger has made world of difference in mine. the other stuff in the vq aquritizing kit seams like extra stuff to charge you more to me

The most noticeable improvement is replacing the sear and trigger with the VQ sear and target trigger. Fairly easy parts substitution. I put one VQ hammer in a MKIII and didn't see any real difference between VQ hammer/trigger/sear and VQ trigger/sear.

The other mod for a 22/45 that "improves operation" is the "slingshot" mod. Remove the detente and spring from the bolt release so you can insert a loaded mag and "sling shot" the bolt to load the round.

I used my MKIII's for a years with the VQ trigger and sear with the mag disconnect. The mag disconnect parts may make the trigger a little sloppier, but I can't see any real affect on the pistol operation since I don't shoot the pistol much without the magazine. Reinstalling the hammer with the mag disconnect pieces is annoying. About a year ago, I replaced the mag disconnects with bushing from Sam Lam. They work great and I don't have to worry about the extraneous parts.

You can remove the LCI, but, IMO, it doesn't do anything except enhance the collection of gunk to the left of the chamber. I don't use it as an indicator for a loaded chamber, since I'm more accustomed to looking at the hole on the other side of the receiver. I haven't done anything with the LCI, see on need to "fix" it, which means that once of these days I'll get bored and remove them.

2245 Maintenance Page is a great resource for delving into the MKIII and MKII.

I hated the magazine disconnect for a couple simple reasons.
1. Magazine dance apon disassembly, and reassembly.
2. The magazines would drop free when loaded.

I've read about dropping the mags but don't recall the circumstances or fix other than getting rid of the mag disconnect. The magazine dance didn't bother me. I could, when the spirit moved me, field strip and reassembly a MKIII in about a minute. I finally decided it was better to get rid of the mag disconnect. I think the trigger works marginally better with the thing out. Besides all 5 of my Rugers now function about the same. Makes it easier on me and safer in the long run.

My MKIII had a stove pipe issue that was very frustrating.
It was even more so when you would get the malfunction, and have to pry the magazine out. VQ makes a little spring loaded magazine ejector that fits in the bottom of the magazine well. It replaces the plastic spacer in back of the magazine. It is supposed to keep constant spring pressure on the bottom of the magazine. When the magazine release is hit, it's supposed to shove the magazine out.

I opted to remove the disconnect instead of buying the magazine ejector.
Killing two birds with one stone, the dance and the prying when I had a malfunction.

Replacing the MKIII hammer bushing with a Clark is supposed to get rid of most all the creep. I opted for the VQ bushing myself.

i picked up the vq bushing because it was the first thing that came up on brownells. using the mark 2 bushing is a lot easier than playing with the washers

Thanks everyone.

I just took the metal hook off the LCI and re-installed it. I also performed the slingshot mod. It works ok but does not seem to drop freely all the time. Some said they install a spring. Where do you install it and what kind of spring?

I ordered the MK II hammer bushing. The VQ sear is back ordered so I also ordered the VQ extractor to be put on the shelf until I feel the need for it.

Since the sear is not available right now, what can I do as far as a DIY trigger job. What surfaces to polish, and what to polish them with? Any links to a DIY trigger job?

I haven't heard many folks who have done well with diy sear and hammer polishing on these.

you can find the sear at Midway Volquartsen Target Sear Ruger Mark 2, Mark 3, 22/45 Stainless Steel - MidwayUSA

and Volquartzen

Sorry. I didn't clarify. I wanted to get the parts from here:

Rimfire Sports & Custom: Ruger Mark II, Mark III & 22/45 Accessories

Cheaper and free shipping comes out about $14 cheaper for the sear so I will wait until they have them in stock.

Meanwhile I had some time to kill so I cut down some washers and got rid of the mag disconnect temporarily until my parts show up. Mags drop out nicely.

So with the LCI tab gone, the slingshot mod and the mag disconnect I guess I've had it apart like 20 times now. I know this pistol inside and out and assy/dis-assy takes like 1 minute now.

The name of the company is Tandemkross. Removal is very easily done with a strong magnet. They have videos showing how to do the mods on Youtube.
