View Full Version : Official Police binding a little on one half of the cylinder

The cylinder of my Colt Official Police at times binds against the force cone a little. Sometimes all 6 chambers have smooth action all the way through, other times, I feel a tad (I really began to notice it when I got my 1961 model back and felt how smooth it goes through the action...you don't even feel the cylinder being pushed) With this 1944 version, I can feel a slight resistance as the cylinder is being pushed...in fact when I am smoothly pulling the trigger slowly, at times I can see the cylinder itself kinda bobble a little while rotating as though meeting resistance (NO IT IS NOT THE BOLT HANGING ON THE CYLINDER NOTCHES) and sometimes it rocks the whole gun a little to where it knocks the sights off target a little when taking aim. Sometimes I don't feel it at all, but suddenly, it will get that feeling. It's to the point now that just about every time I use the gun after firing 6-12 shots, the resistance gets to the point where I can barely sqeeze the trigger through to finish the action. I have to sqeeze the trigger as hard as I can at times to push the cylinder through.
When I look at the front of the cylinder, I see the bluing on one side of the rim having been worn away, when I look at the force cone, I see a small area that has had some metal rubbing against it.

Any thoughts on this (NO I SERIOUSLY DON"T THINK IT IS ANYTHING UNDER THE EJECTOR ROD, I HAVE CLEANED UNDER IT UNTIL I WAS BLUE IN THE FACE AND ALSO IT DOES THIS ALL THE TIME)

I am thinking about sending the gun off to Pittsburg Handgun HQ to 1) get this problem solved and 2) maybe widening the force cone a little as it has seen alittle wear and to also to give the gun a little more accuracy.

Any thoughts

Thanks,
Doug

It sounds like the crane is bent.

Probable sprung or bent crane, and possible end shake as a contributing factor.

Pittsburgh will fix it properly.

end shake? What's that? Sprung crane?

I have also noticed (I don't know if this is a problem) that when I slowly rotate the cylinder with my finger as it hangs from the side of the gun that it will sometimes wind back a tad counter to the way I am turning it as though the spring inside is resisting it. Yet is doesn't do this on my other OP

End shake is a condition in a revolver that allows the cylinder to move back and forward. A very slight amount is normal, but if excessive it can allow the cylinder to bind on the barrel or even strike the barrel when closing the cylinder.

The crane is the part of a revolver that supports the cylinder as it is swung out for reloading. The part of the crane that the cylinder revolves on is called the arbor. It must be in perfect alignment or the cylinder will be out of alignment and the condition described will result. A bent ("sprung") crane or arbor is usually the result of either slamming the cylinder closed (the old movie trick, where the character closes the cylinder with a flip of the wrist) or using the gun to strike a blow, usually on someone's head (a common problem with ex-police guns).
