Northern Xtreme Posted October 4, 2009 Share Posted October 4, 2009 I picked up a Ruger 22/45 MK3 for my son to learn how to shoot a Pistol on. I am a little dissapointed that the mags do not drop free. Is that because it is a MK3 and has a magazine safety, or are the MK2's the same way? I've not handled a MK2.

mscott Posted October 4, 2009 Share Posted October 4, 2009 I have 2 of the MK2s and all my mags drop free. Not sure about the MK3. Link to comment Share on other sites More sharing options...
Northern Xtreme Posted October 4, 2009 Author Share Posted October 4, 2009 I have 2 of the MK2s and all my mags drop free. Not sure about the MK3. Does the MK2 have a magazine safety that will not allow the pistol to fire without a Mag? Link to comment Share on other sites More sharing options...
pevadijk Posted October 4, 2009 Share Posted October 4, 2009 I have a MKIII 22/45 and if you remove the mag safety, the mags will drop free. Do do this I've installed a MarkII hammer and hammer bushing and replaced the parts, that's all. Link to comment Share on other sites More sharing options...
Duane Thomas Posted October 4, 2009 Share Posted October 4, 2009 No, the Mk II does not have that feature. Link to comment Share on other sites More sharing options...

Great, Thank you! Thats what I suspected the problem was. So just a hammer and hammer bushing? I noticed a strange lever on the back of the trigger that I wondered about dremeling off, or I was going to replace the trigger with an adjustable Volquartsen type with set screws anyhow to take some of the awful creep and overtravel out of it. Other than that are the MK3 mags fine? Can you use MK2 mags? Link to comment Share on other sites More sharing options...
pevadijk Posted October 5, 2009 Share Posted October 5, 2009 (edited) I don't know if MKII mags will fit. The MKIII hammer has a machined slot for the mag disconnect and the spring (part 36 and 37 on the parts diagram), when you just remove these parts the hammer will wobble. If you replace your hammer with a MKII version and a MKII hammer bushing the mag-disconnect is gone and it's done in a few minutes without modifying any parts. I just looked at the Brownells website and it seems that the Mark II hammer bushings have been discontinued, but Clark also sells these bushings. Here it's explained with pictures! http://guntalk-online.com/forum/viewtopic.php?t=634 Also usefull http://www.rugerforum.net/showthread.php?p=167289 Edited October 5, 2009 by pevadijk Link to comment Share on other sites More sharing options...
Northern Xtreme Posted October 5, 2009 Author Share Posted October 5, 2009 Excellent, very useful information. Now I can make the new MK3 22/45 into something that my son can learn to shoot USPSA with. Link to comment Share on other sites More sharing options...

North Posted October 6, 2009 Share Posted October 6, 2009 Here's how to make your own magazine safety spacer washers to remove that pesky magazine disconnect safety from a Mark III pistol. Use common tools found in most home workshops for this modification. No lathes or mills were used to make these spacers. Tools: 1 pr large wire cutters (dike pliers) 1 fine bastard file 1 #2 Phillips head screwdriver 1 Meduim adjustable (Crescent) wrench 1 Drill press ( hand drill mounted carefully in a vise will work) 1 bench vise 1 Sharpie brand permanent marker Materials: 2 #10 SAE flat washers $.06 ea. from local hardware store 1 Stainless countersunk machine screw 1 machine nut with integral star lock washer Two SAE #10 flat washers will do the trick. You can use steel or stainless. http://www.guntalk-online.com/forum/viewtopic.php?t=387 Link to comment Share on other sites More sharing options...
kamikaze1a Posted October 7, 2009 Share Posted October 7, 2009 From what I am reading here, this and a bushing to disable the mag safey on the MkIII? Link to comment Share on other sites More sharing options...
Northern Xtreme Posted October 21, 2009 Author Share Posted October 21, 2009 OK I got the bushing from Clark. Now I want to get a Volquartsen trigger kit because the stock trigger is sooo bad. Should I order the MK2 or the MK3 trigger kit? I would like the use bolt release because my kid has a little trouble releasing the stock one. But from an earlier post I got the impresion that the MK 2 kit release wouldnt work on the MK3. Does anyone have any advise for me on this?

The bolt release that comes in the trigger kits doesn't fit the MKII or MKIII 22/45's it is only for the MK Steel Frames. Link to comment Share on other sites More sharing options...
Litlratt Posted November 21, 2009 Share Posted November 21, 2009 I can vouch for the Sam Lam bushing. It works well with the VQ MKIII kit. Link to comment Share on other sites More sharing options...
