The 1st washer I made for the MKII hammer bushing to take up the slop from the removed mag disconnect was a quick fix and it really didn't fit right. The washer was only ~.038" and the cut out in the hammer for the mag disconnect was about ~.043". I replaced the single washer with 2 smaller diameter...

I ended up making new [better] washers to put in place of the Mag disconnect lever and that dropped the trigger pull from 3# 14 oz to 3# 4 oz. Next I lightly flat stoned the sear and trigger then polished all trigger componets with JB paste. Trigger pull then dropped to avg. 2# 3.5 oz. I think I'm g...

Has VQ changed their sear design ? My MKIII VQ parts were bought and installed in 8/2007. I bought the 22/45 VQ parts October 2012. Would I just be better off just buying a new VQ Target Hammer for the 22/45 that would hopefully be match with the VQ sear ? I didn't think to buy a VQ hammer in Octobe...

Bullseye wrote:Generally the new parts result in a two pound average pull. When you say you installed the same parts in a MKIII678, did you mean the exact same parts or similar ones from another VQ kit?

I installed new parts from another VQ kit....

I installed a VQ match trigger, sear, and MKII hammer bushing in hopes of greatly reducing the trigger pull like I did on a MKIII678. I’m miffed that the pull only decreased from avg. 4# 9.2 oz to avg. 3#14.2 oz. When I installed the same VQ parts on my MKIII678 the trigger pull changed to avg. 1# 1...

I'm curious why Ruger came out with this .22 LR model. For center fire models [I have the .357 mag] the SP101 is great; however, with the Ruger MKIII and 22/45 line with 11 round vs 8 capacity I see no reason for it. Any ideas ?

You all were right, my problem was the trigger pre-travel adjustment screw. I forgot all about it and neglected to Locktite it when I installed it almost 4 years ago thinking I might want to make adjustments later. Another lesson learned. Thanks again guys.

Oops, forgot to mention I removed mag safety & LCI when I put in a VQ match trigger & sear and a Clark hammer bushing. The trigger is all the way back, like immediately after firing, and feels locked in place and cannot be moved forward. Been a long time since I've had it apart..... Is the pre-trave...

After shooting ~ 50 rounds at the range, the trigger became inoperative [like the trigger did not reset]. I removed the magazine, pulled the bolt back to eject the chambered round, then started to disassemble. I got the mainspring unlatched but it will only come out about 5/8"; not enough to allow i...

Also, are there any roomers yet about a SS RP model ?

I used the RP grips to make my molds going to make a set a little thicker to give the same thickness as my 1911 will post a picture when I have them made. Will the existing RP grip screws support thicker grips ? Are the grips screws stock 1911 or a common size that one can get longer ones ? It woul...

I'm disappointed to hear the MKIII 22/45 RP grip thickness lacks ~.180" [3/16"] from being the same as the 1911. It's unfortunate Ruger couldn't get it right.
Does anyone happen to know the thickness of the MKII 22/45 grip ? I may have to put one on my gun show wish list.

Perhaps I can find some thick 1911 grips that will bring the grip thickness closer to that of the MKII or 1911.

How does the grips/frame width compare to the regular MKIII 22/45 ? I'd like to have a 22/45 that has a grips/frame width similar to the old MKII 22/45 . The MKIII 22/45 frame is just too thin.

Although there wouldn't be an adjustment screw for fine tuning, couldn't one just move the MKI magazine up and down to hit the spot were the ammo glides into the magazine ?
