SP-101 Owners: Do All SPs Do This?

Just noticed that when I pull the trigger in double-action mode, the trigger housing moves away from the frame just slightly. Just enough to slip a bit of paper into the crack:

It happens also on the left side of the gun, but to a lesser extent. The gap disappears when the trigger hits full-reset.

Does everyone else's SP101 do this too, or is it something I should keep an eye on?

The gun shoots perfectly.
I did fully disassemble and polish the internals, but I only used a soft Dremel wheel with rouge, so there's no chance I could have deformed any of the parts. Installed something backwards, maybe.

If y'all could check your guns and see if this is normal, I'd appreciate it much!

Thanks,
Ivan
 
Remove the grip to see if the plunger that holds the guard ass'y. in place is out all the way. Rap the rear of the guard soundly with something that won't leave a mark on it. A nylon hammer works best, but the butt end of a large screwdriver handle will work. That should close up the gap. If it doesn't, or if it happens again, it might be time to have someone that is familiar with Ruger DA's look at it.
 
more importantly whats up with that hammer? is that like some new cast or MIM part? :confused:

Nevermind googled it. damn. that just looks icky.

I think your frame is within spec. its not ideal but should be fine. call ruger and ask if your concerned.
 
Thanks for the replies so far! Trigger return spring is stock, trigger link plunger and trigger latch are in their proper places and properly engaged.

Oldgunsmith, you may have misunderstood my original post. The trigger housing moves away from the frame every time the trigger is pulled, then returns tight to the frame when the trigger is released.

What seems to be happening, is that the tension of the trigger pushing up against the hammer dog to cock the hammer is pushing the entire trigger assembly downwards and creating the gap.

Measured the gap with a feeler guage, at it's widest point it's .006.
 
That's not normal. I don't know what's causing it, but it shouldn't do that.

I'd send Ruger an email with a link to this thread.
 
Just submitted an inquiry via the online form on Ruger's website. Didn't think to link this thread on there though, that would have been a good idea. I will let you guys know what they say.

And a slight correction on the gap size, it's .007". Measured with a feeler gauge.

Thanks all,
Ivan
 
The plunger that holds the trigger guard assembly is suppose to be tight... pulling the trigger assembly toward the frame at all times. I bet if you pull on the guard you can create the gap manually. It is defeniately a defect that Ruger should be notified of.

My guess is they will replace the trigger guard assembly. The easiest way for them to fix the problem.
 
Ruger replied to my online request and told me to call them for an RMA #. So I did, off it went to them today.

I got this gun ten days ago as a warranty replacement for a different gun that failed within a few weeks of purchase, I just seem to have no luck with guns as of late!

I wonder if it has anything to do with the fact that this thing had the number 13 scratched into the frame and trigger guard.
 
You did the right thing.
Ruger has a great CS department. You should have no problem getting it fixed.

Keep us posted on the outcome.
 
How you doing Mr James? I saw the opportunity. :D. OP none of my sp revolvers do that. Sorry your having trouble with a fine revolver.
