How picky is your Ruger MKlll?

I had a few problems with mine but they all went away when I replaced the factory extractor with a good one. I shoot the cheapest thing I can buy and I might have a malfunction every 100 rounds or so.
 
I have several and they eat just about everything except Remington Gold Tips. The few times I have had issues it was magazine related. There are some good videos on youtube that demonstrate magazine polishing and tuning. The magazines I had issues with all feed fine after tuning so it wasn't a pistol issue but a magazine issue.
 
The dreaded LCI

Mine was a jam o matic removal of the little tab for the loaded chamber indicator took it from 80% to 99%.
The LCI is easy to disable. Google is your friend.
 
Mine is not picky, to give you an idea, I've put thousands of Thunderbolts through mine over the last 12 months and only had one or two malfunctions.
 
This Ruger Mark III Hunter runs just great! It did take a while to get the springs settled, but once they reached their working "set", this pistol doesn't miss a beat as long as fairly decent ammunition is used.



I've run CCI Blazers and Federal Auto-Match bulk on a regular basis, and will get an ammunition hiccup every once in a while with the Auto-Match.
 
I have 4 of them and cant remember the last time I had a malfunction. I did break off the tab of the LCI, just like someone above said, and dumped the mag disco. I also did the magazine tune up on all my mags.
 
In Post #11, "rick in VA" wrote of getting "lead smilies" in his ejection port from bullets shaving when entering the chamber. That condition really has nothing to do with the feed ramp. When that condition is found, you need to check the rear chamber mouth and its edge on the chamfer going into the chamber. That chamfer is often found to have a sharp burr from the chamfer being machined. When a round is fed from the magazine, the bullets bearing surface will scrape against that burr and shave a half-moon of lead off the bullets bearing surface. Not very conducive to helping accuracy when the now, unbalanced bullet hits "free-flight" after leaving the muzzle. Carefully polish that chamfer into a smooth, shiny radius and the "smilies" will go away.

 
With four Rugers in my inventory and shooting whatever .22lr ammo was available, I've had almost no problems. Except for a Mark ii Government Target Model which I bought used. It had both extraction and ejection problems. Replaced the extractor, didn't help. Sent it to Ruger CS. They cleaned it, replaced the extractor, ejector, firing pin and some springs and drilled and tapped it for rail mounting. Removed the extractor and shipped it back to me. No charge! I paid freight to get the gun there.

The gun still isn't exactly right. Like Radny97 said, I find the Aquila 40 gr RN copper coated ammo to be excellent. I plan to run several hundred rounds of it thru the Mark ii to see what happens.
