I have a Ruger Mark II, I took it appart for some serious cleaning....Took the barrel off, used powder solvent, oiled it then put it back together. Picked it up and turned it, and there was a slite rattle, as if something is loose, or doesn't fit tight. Tore it down, put it back, same thing. Tore it down, put it back same thing, this time I pulled the trigger(empty of course) and it want away. Cocked it(pulled the slide back and released) and the sounds back. This sequence has continued. Anyone have any ideas? Cousing thinks something might be wrong with the firing pin. The springs loose or something, but thats just a guess.

I also don't want to shoot it until I get this figured out.

thanks 189..
 
OK, I know nothing about Rugers so this might be way off. On Glocks, when the trigger has been pulled, you hear a rattle as the striker moves in the channel. Perhaps the firing pin in your Ruger is moving about as it should.

Also sometimes I've had trouble with clickng empty magazines in SIG Sauer and S$W pistols. Do you have an empty magazine inserted in the pistol when you hear the sound?

------------------
So many pistols, so little money.
 
Let me start by saying that I don't think you're supposed to remove the barrel from the receiver, as Ruger describes them as an integral unit. Don't know if you did this or not.

If you disassemble the gun, the firing pin is visible within its spring, in the top of the bolt. Any rattling, movement or looseness of this part should be visible. There is a piece of metal that hangs down loosely from the rear of the "hammer" that may move slightly from side to side when the gun is assembled.

Be sure that you have followed the reassembly procedures EXACTLY as they appear in the manual. Proper reassembly requires holding the pistol at certain angles during reassembly so that the parts are in the correct position when mainspring tension is taken up.

Hope this helps.
 
First thanks for your postings, second I didn't have the magazine in so it wouldn't be that even though it sounds like another good reason.

The barrel is screwwed into the reciever and they aren't suposed to come appart but the reciever can come off the trigger housing and grip. Also I believe I put it together correctly, atleast the way I hyave always done it with this being the first time i have heard the noise.

can anyone add to what ledbetter had to say about the hammer and bolt assembly? I would appreciate it.

thanks agian 189...
 
Call ruger and they will send you an owners manual. These pistols are relatively hard to put back together , even with the manual. I can now put mine back without the manual most of the time. Step 1 hold the grip assembly normally. Make sure the hammer has fallen back into the grip assembly and slide the barrel assembly on. Holding this together with your left handtilt the whole thing up so that the barrel is pointing straight up in the air, and pull the trigger. This causes the hammer to return to a cocked position. Keeping the gun in your left hand hold it level againand sliide the bolt in. Now point the muzzle to the ground Not straight but withh a slight angle 35 -40 degree and pull the trigger this will cause the hammerto fall into the bolt in it's uncocked position. When the hammer falls you should hear a click. Now let go of the trigger and bring the gun level again again holding all of this crap together. And slide the bolt stop pin up into the gun. This is the latch assembly at the rear of the grip.with the pin up in there tilt the muzzle up about 35-40 degreesand swing the latch into the grip frame. At this step you shoud feel resistence for about the lat 1/8 of an inch. If youfelt the resistence latch it closed and you should be good to go. If not the bolt won't cycle. Good luck and call Ruger for the manual. Even with it , it took me 3 or 4 times to get it right.
 
If you can pull the bolt back you probably put it back together correctly. I just tore my new MK II down for the first time the other night. The directions from Ruger aren't great, but if you have taken it apart before you probably have the trick figured out. The only suggestion I have is to take it apart - inspect the hammer and internals for anything loose. Turn the grip frame at different angles to hear where the noise might be coming from. When you put it back together make sure the hammer is laying down flat when you slide the barrel back on. Then make sure that the hammer strut goes back into the slot in the mainspring as you close it back into the grip. I don't think there is much you could hurt on one of these guns. If you put it back together incorrectly you know right away. I was actually surprised at how easy it was (took me a couple of trys) - Ruger needs to make the hammer strut into the slot section more clear, maybe a larger picture that shows the relationship more clearly. There are two websites that show the reassembly that I've found. Neither is great.

One last thing. Make sure that the firing pin block is in the bolt. That is very important.
 
After you insert the bolt stop pin, the hammer strut must be properly placed against it before (as) you swing the latch closed. You failed to properly position the hammer strut, and this is what is causing the noise that you hear. When properly reassembled, you will hear a click when you press the trigger, but after you cycle the bolt and dry fire it once, the click will not reoccur. If it does, the strut is not properly placed.

When did they start putting a screw in the barrel? All of them I have seen just friction fit to the frame.
 
Hi, numbers,

Did you lose the firing pin spring or not put it back in properly? If so, the rattling is the firing pin. You won't hear it when the hammer is down, but it will rattle with the hammer cocked.
