Just completed trigger & sear upgrades.

[RichM]

I just upgraded my Ruger Mark III Stainless Competition Slab-side follows:

• Added the Volquartsen spring-loaded magazine ejector;
  
• Replaced the extractor with the VQ extractor;
  
• Replaced the sear with the VQ target sear;
  
• Replaced the trigger with the VQ target trigger;
  
• and installed the VQ extended bolt release.

I also have the VQ extended magazine release, but I think I need to polish it just a little; the magazine fits a little too tightly with it in and doesn't insert or eject smoothly.

I'm also waiting for a hammer pin bushing to remove the magazine interlock "feature."

... and I removed the loaded chamber indicator...

I needed the extended bolt release because the stock lever folds over the cocobolo thumb rest grips and I can't get my thumb under it to lock the bolt open when it's not on an empty magazine (e.g. "cease-fire and clear" during competitions); I need the extended magazine release for a similar reason (I can't reach it around the grips for fast magazine changes).

The new trigger is SWEET! I can make both pre-travel and post-travel adjustments on the trigger without disassembly.

And the magazines just shoot out of the well with the spring-loaded ejector!

Nice! I just did the exact same thing with my Mark 3 with a different choice of parts. I went with Clark for the trigger/sear. I also installed the the bushing to remove the magazine lock.

I'm assuming yours is the standard Mark 3 since you could use the extended bolt release. Mine's the 22/45 so I can't use that as much as I would have liked to. I did get to add 1911 grips to mine.

Let's see some pics of yours! I haven't seen a slab side one in a while.

Pics!

Here's the pics:

* Mrs. RichM says it's hers, but it's still in MY name!

22/45 Mods: Extended Magazine Release, VQ Sear, VQ trigger, and VQ edge extractor. Both loaded chamber indicators have been removed.

Target Slab-Side Mods: Extended bolt release, spring-loaded magazine ejector, VQ Sear, VQ trigger, and VQ edge extractor.

I have the extended magazine release for the slab-side, but I need to work it a little to take out the binding.


BTW, did you ever do the grips mod on your 22/45? I don't think that I ever saw any pics...
