Locked Up Revolver

[Jackalope]

Anita Margarita was intermittently unable to fully cock one of her Ruger Single Six revolvers during a match yesterday.  Something was binding up the hammer somehow.  When the grip panels were removed this morning, a small coil spring fell to the table.  Upon further disassembly, another small part was found floating around near the trigger/hammer engagement notches and the bolt.  As it turned out, the little plunger and spring were originally part of the cylinder pin designed to keep the transfer bar from hanging up on firing pin.  Once they worked their way free of the cylinder pin, they migrated inside where the plunger eventually became bound between the hammer and the frame, effectively preventing the hammer from being cocked fully.  These Rugers had been short-stroked by Boomstick Jay many years ago and, since he had removed the transfer bars, the spring and plunger were no longer needed, nor were they held captive inside the cylinder pin.  Once the foreign objects were removed, the gun works fine again.

The cylinder pin on the left shows the spring and plunger that fell out.

Spring and plunger are staked in at the factory, I'm surprised they were able to come out of the cylinder pin.

First time I have ever seen one come apart like that.

It must have been all the severe and violent recoil of the mighty .32 H&R Magnum that finally pounded the staked divot loose.  😁

Shotgun Boogie pulled the plungers and springs out of my Bisleys when he short stroked them. At the time I wondered why, now I see it is probably a very good idea.

 

Thanks

Years ago like mid 80s bought a model 66 smith did not shoot it much but in circa 95 when I was at el paso I was shooting it one day at FT Bliss Rod and Gun Club range.  Locked up tighter that a drum.  Knowing nothing of S&W double actions took it to a friend.  Pulled the side plate and found a big machining chip had worked its way under the part that rocks up and down when trigger is pulled.  Still know nothing of S&W DAs or would have correctly named the part.  Am amazed that the chip stayed in the gun during manufacturing one would think it would have been washed out when they rinsed out any cutting fluids or at worst spotted when the gun was being assembled.  Oh well never a problem since and has been shot a lot more than it was in the first 10 years of its life.

Just like a dang jackhammer I imagine. 😉
