Part Two: NIB Ruger jams

[ACP]

So I ran another 130 rounds through the gun tonight, using both magazines.
Long story short, 4 stovepipes in 130 rounds, which equals a 3.07% failure rate. MUCH better than Sunday.

I cleaned the gun and the mags., then shot 10 rounds each of the following, alternating magazines but using the exact same Rock Jr. rest:

Blazer 40-gr. RNL
Remington Golden Bullet HV plated RN
Federal Game Shok 40-gr. copper-plated solid
American Eagle HV 40-gr. solid RNL
Federal Champion bulk 36-gr. copper-plated HP
Eley Target (5 rounds each magazine)
10 MIXED ROUNDS randomly inserted in magazine

Mag 1 (the one I used the other night) had a single horizontal stovepipe: a first round with the Fed. Game Shok (which is a nice round, BTW)

Mag 2 (which I had not used before) had 3 horizontal stovepipes -- 3rd shot with the Blazer, and 1st and 4th shots with the Federal Champion bulk.

Both magazines/the gun performed flawlessly at the end, shooting (freehand) 10 rounds of mixed ammo without stoppages.

If I had my druthers the trigger would have much less take-up and be lighter, esp. for the first shot, but at least the stoppages (with Fed. bulk and American Eagle) have decreased dramatically.

I now have about 230 rounds through the gun, I will double that before deciding if the pistol needs more attention.

Thanks for all your input!

I'd put at least 500 rounds or so through it before worrying about it. The MK series are excellent guns and if you keep having issues after break in call up Ruger and see what they say. On a gun that new they'll probably cover return shipping. My Ruger MK3 has had zero issues (well over 10k rounds) but some of them may need a few rounds to help smooth out the insides. I try racking the slide a bunch on some guns when I first get them to smooth out the slide/frame fit some and then I clean them.

I agree. Run 500 rounds through it, then thoroughly clean it and see what your results are.

BTW, I am amazed that you have access to that many different types of .22lr!


HEY! 6,000th post!

Send the gun back to Ruger. A gun should run perfectly out of the box. No one should have to spend $100 on ammo with a new gun in order to make it run. Chances are it won't be much if any better and you are just out the cost of the ammo. If it were my gun UPS would already have it on a truck back to Ruger.

At this point something may be wrong. Contact Ruger and present your problem with the facts you have. DO NOT ALTER your pistol until it is back from Ruger and running perfectly.
Then install the parts to make your gun a magnificent shooter.
