Uberti 1849 Pocket Model cylinder over rotating

Trum4n1208 · August 4, 2016, 03:48 PM

Howdy all,

I asked this over on the CAS forums, but it never hurts to ask around, so I figured I'd ask here too.

I was looking in my favorite LGs when I cam across an Uberti 1849 Pocket model for a decent price. I've been bitten by the BP bug, so I'm certainly intrigued by this revolver, but I had a question (I should also note that I'm aware that the pocket models tend to have more problems than the average Uberti BP pistol, but it'd make a perfect companion to my 1851 London Model, so I've got to give it a try). I noticed that if I cocked the piece with any kind of authority, the cylinder would over rotate just a bit. Not a problem if I cocked it slowly.

I'm still a bit of a newbie to these guns, so I'm not quite sure what the issue is, it's not one I've experienced with any of my other 'Old West' guns. Is this indicative of a bigger problem? Is this a potentially easy fix?

Thanks for y'all's time, it's greatly appreciated.

when you cock it fast the cylinder carries more inertia over riding the bolt stop. this could be a weak or broken bolt stop spring. that would be a simple fix, if it is a bolt stop or hand problem things get more complicated as those parts are not drop ins and require fitting.

It could also be a problem with the bolt coming up late. The bolt should make contact one full bolt width before the cylinder notch. If the bolt is coming up on the edge of the notch the notch may be peened and the bolt just can't get enough of a bite when it's cocked fast. All relatively easy fixes IF you understand how a single action works and are familiar with the insides. It wont be the hand because if the hand is too long and the bolt is timed right the hammer won't go to full cock.

While Pettifoggers articles are based on the Pietta 1851 Navy, the internal workings and processes for tuning the action are the same for the Uberti pocket models.

Read those then read these on tuning the Uberti Open Top Revolver. The author refers back to the Pietta pages.

I tuned my Pietta 1860's a couple months ago. Just fitting the bolt to the locking notches on the cylinder made a huge difference.
