bearcat miss firing

[boot strap jack]

Tweet

picked up a used bearcat, it misfires 3 or 4 times on a cylinder full. Gun was worked on by a smith for action job and the rear sight notch widened. I think the hammer spring is to light to overcome the firing pin return spring. With cylinder out and base pin reinstalled to keep the transferbar from hanging up no firing pin, I can fire the pistol and watch as sometime it barely clears the frame. I can push the hammer foward and make the pin move farther out. So what are the ideas out there, and fixes.
Thanks BSJ

Went ahead and tore into it. The hammer spring was cut, and a poor job done of it. Went ahead and stretched it out, and replaced it. Test fired and it worked with full cylinder. now need new spring and a spring compresser to do it proper.

Contact Ruger or Gun Parts Co - www.gunpartsco.com - and they'll have the needed parts.

As you've found - a lot of 'gunsmiths' - aren't...

'Any' time that someone says that the piece has been 'worked over by a 'smith' is a good time to negotiate the asking price downward.

SG, I'm not a smith but I'm of mechanical aptitude, And the work done by whom ever did not show much to me. I can fix it myself for a couple of bucks and shipping, as my temp fix probably won't hold up.

I'm going to add this, often times folks install lighter springs and never do any of the deburring/polishing of all internal parts that is often needed more than springs.  I here a lot about guns that will only fire with Federal primers reliably.  I know I'll upset some, but that is a broke gun, I would not have a gun that would only fire certain ammo.

I tuned up a SSM Ruger 32 mag, with the lightest main spring and it will fire even the small rifle primers often used in the heavy Ruger only loads, each and every time you pull the trigger, even CCI's.

If you've figured out how to take it apart and reassemble it without screwing up the finish and the screw heads - you're doing as well as a helluva lot of back room 'gunsmiths' out there.

All your Bearcat's going to need is a de-burring/stoning and a good lubricant - and of course, the new spring, and given how smooth they are from the factory - I'd imagine that the de-burring/stoning won't be necessary.

In case it may be warranted - look for any 'high spots' and carefully stone them away, without changing any factory angles.

Again - Good Luck - you're on the right track.

Have a new spring on the way. If this one gives out I will open her up again and hit the high shinny spots. This and the oyher one that arrived today will be for my 11 year old daughter to use. This one did have poa done, and is good out to 30 yards, on pop cans.
