New SP101 problem?

I bought a SP101 a couple of weeks ago and finally got a chance to shoot it. First 2 rounds did fine but on the 3rd the hammer stuck forward (wouldn't let me pull trigger double action). I pulled the hammer back and let it fall and it worked double action again. It did this 4 times out of a half box of ammo.:banghead:

I probably need to send it to Ruger, but was wandering if anyone had an idea what the problem would be?

Look at your fired brass and see if the primers are extruding into the firing pin hole.

Just looked at the brass. They look normal. I compared them to some brass i know was shot out of my GP 100,they look the same. I was shooting Remington .38+p factory ammo.

Weak spring on the double action bar (hammer dog?) on the hammer, or the bar/plunger is jamming. Field strip and check it for binding or burrs.

It COULD BE a very common problem with new owners of Ruger DA revolvers - short stroking the trigger. If the trigger is not allowed to reset ALL the way forward the action will lock as you described. Most other brands allow you a little bit of slop regarding less than full reset but not Ruger. Your finger has to come all the way forward until it almost hits the trigger guard. My wife went through this during her "learning period" with her new GP 100. I have seen quite a few other people experience this problem. Don't blame the gun until you have positively eliminated the possibility of not allowing the trigger to reset. Like I said, this is a very common complaint, especially if the gun has been re-sprung with lighter springs. If a light spring kit is installed with a lighter than stock trigger return spring it can slow down the trigger reset enough that it seems like you're having to "wait for it" - because you are. This is precisely why Jerry Miculek uses stock or stronger springs in his revolvers. He is more than willing to put up with a higher pull weight if it allows him to cycle the gun faster - and it does.

I'll give that a try before i sent it in Draill. I don't have any problem with my GP, but i guess it could be a lighter spring in the SP101.

could any of it be related to the built in lock the have in the grip at the bottom of the hammer spring?

The SP101 doesn't have an internal lock.

Wow, they put a lock on the lcrs but dont on the sp101s? That is odd.

LCR is a much more recent design. The SP 101 was designed years before internal locks became standard on almost every gun. LCR came after the lawyers finally took over the universe. We are doomed.

The Single Six was Rugers second gun design. It was designed way before there were "Lawyer Locks". Some of the Single Sixes have internal locks. Go figure.

A buddy of mine had a similar problem with his GP-100: He and I were at the range when on the third round the trigger failed to reset and remained at the most reward position, but the hammer could still be manipulated, so he pulled the hammer all the way back and let it slam forward; the trigger sprung forward and the DA worked again. We shot another cylinder and problem came back and from that point it became successively worse.

He sent it to Ruger and they fixed it right up.Yet even now I still don't what the exact problem was, and Ruger never sent a list saying what was replaced. I assumed it was fitting issues of the transfer-bar.

Edit

Here is a thread that might help you. (http://thefiringline.com/forums/showthread.php?t=436224) it's from the Firing-line.

Got to the range this morning. Just to make sure i wasn't short stroking the trigger, i fired each shot and took finger all the way off it each time. out of 25 rounds it bound up once. Primer looked seated properly.

Anything else i should look for?

I always check here first, y'all are always a big help. Thanks

Probabaly a weak or broken trigger return spring. Ruger will fix it at no charge no matter what it is.

So were the Blackhawks, and the recent ones have internal locks.
