Sarge Posted February 6, 2019 Share Posted February 6, 2019 I am going to give Gunfighter a try this year. I have a new pair of stock short stroked Uberti Running Irons with the short hammers. I've gone through and cleaned up the rough edges and they feel pretty good. Have been dry firing daily with snap caps in place. The gun that I've dedicated to my left (weak) hand seems to glitch every once in awhile where it feels like the gun wants to start locking up before the hammer is all the way back. I notice when this happens, the muzzle is slightly above level when I cock the gun. If I drop the gun back to level, the gun is very smooth. If I swap the gun to my right (strong) hand, the problem does not seem to occur with the same frequency, though it does still occur every so often. Does not happen with the gun I've dedicated to my right hand. Timing seems to b right, can't find any burrs anywhere. Is it just me not quite having the gun properly aligned? Gun problem? Technique problem? Link to comment Share on other sites More sharing options...

Badlands Bob #61228 Posted February 6, 2019 Share Posted February 6, 2019 I have a different problem. My left hand is blind. Link to comment Share on other sites More sharing options...
Flash Posted February 6, 2019 Share Posted February 6, 2019 My guess would be the snap caps are catching. Does it do it when you shoot? Link to comment Share on other sites More sharing options...
45 Dragoon Posted February 6, 2019 Share Posted February 6, 2019 I think Flash is on the right track. The Uberti's tend to have a more abrupt step up to the breech face as the round going into battery reaches it. You will need to radius the edge of it for a smoother transition.

Grizzly Dave Posted February 6, 2019 Share Posted February 6, 2019 I certainly wouldn't start grinding until a fair amount of live fire practice and give those pistols a chance to get broken in. For myself, I can generally trace any problem back to me, so that's where I look. Just a total shot in the dark here, but can you observe, or video your practice so that you can see if there's any difference in your thumb stroke when the problem occurs? Maybe not getting high enough on the hammer and pushing it to the side or something causing the path of your thumb to create a pause or bind. Does the problem get worse as you get tired? Just a thought. Link to comment Share on other sites More sharing options...
Texas Lizard Posted February 6, 2019 Share Posted February 6, 2019 Any medical problems with hands or tightness....Warm up and loosen the hands/fingers...Just a thought to add the thinking...Or everything is good in this area...

The Rainmaker, SASS #11631 Posted February 6, 2019 Share Posted February 6, 2019 Start by taking away each suspected problem (hands, guns, snap caps, positioning, etc.) You have already switched hands and it still happens (although less). Try keeping the muzzles below level and see if positioning has anything to do with it. You have said that the other pistol doesn't do this (even in the left hand?). If the answer is no, then I would think it's something to do with WHAT you have in hand (gun+ snap caps). Try switching the snap caps in the guns. Does the problem move to the other gun? If yes, then it's the snap caps. If the problem stays in the "left" gun, it IS the gun and will need a further look. Methodically break down the problem and I think you'll find the answer. Best of luck. Link to comment Share on other sites More sharing options...
July Smith Posted February 6, 2019 Share Posted February 6, 2019 As Flash and 45 Dragoon have already indicated the step Uberti in all their wisdom leaves on the recoil shield caused all sorts of binding for me. https://youtu.be/RrZ4Kkgkyu0 If you skip to about the 1min mark you will see what area we are talking about. Snap caps seem to hang up worse than live ammo because the primer area tends to get a little high. Link to comment Share on other sites More sharing options...
Sedalia Dave Posted February 6, 2019 Share Posted February 6, 2019 Easy test remove the snap caps and see if the gun still has a hickup. Firing a few times without the snap caps is not going to damage the pistol. Link to comment Share on other sites More sharing options...
MBFields Posted February 6, 2019 Share Posted February 6, 2019 Uberti's do not have a recoil shield anymore. Check to see if hole for hammer is smooth. it is punched through and the edges may not be smoothed down. Also check the cylinder lock. Will have to take hammer out but sometimes the little angled nub is not engaging the lock enough every time and need to tweak the lock arms a bit.

The Original Lumpy Gritz Posted February 6, 2019 Share Posted February 6, 2019 Do a live fire practice before you start messing with the gun. Let a 'known' GF'r give it a go. Switch guns and see what's, what. OLG Link to comment Share on other sites More sharing options...
Turkey Flats Jack Posted February 7, 2019 Share Posted February 7, 2019 you've already gone through them. meaning you've had them completely torn down and put back together. The key here to me is when the gun is slightly off level is when the problem happens. If it's not something as simple as it's binding up on the snap caps i'd say tear it back down and pay close attention when putting back together. I've had similar problems when working on my remingtons. Simple as a spring not quite centered/lined up exactly right. I recently had a trigger/bolt spring on a new gun not line up correctly when reassembling. Every time I eased the hammer down the cylinder would back spin slightly. The trigger spring wasnt catching right and would let the bolt/stop drop just enough to let the cylinder spin. I know it's not the same problem you're having but not having everything perfectly lined up can cause a few different issues. Good luck and hope you figure it out.

Sarge Posted February 7, 2019 Author Share Posted February 7, 2019 Thanks for all the great ideas. I probably have about 500 rounds through the gun. Have not had a chance to get back out with the guns recently due to weather and a new job taking up a lot of time. Weather permitting, hoping to put some rounds through it this weekend. I do have some problems with my hands, a bit of arthritis in both, but the right hand as other and a lot worse problems than the left. The thing that caught me was the positional aspect the the issue. Link to comment Share on other sites More sharing options...
45 Dragoon Posted February 7, 2019 Share Posted February 7, 2019 Yes sir, position sensitive is "key" to looking for certain known problems. One of the most common would be (from your description) the transition to the breech face. The video link provided by July Smith is an excellent visual and explanation of the problem. You can test for this simply by pointing the muzzle straight up and rotating the cyl by hand. Watch the cartridge heads as they transition from the recoil shield to the breech face. Some of the rims with sharper edges may "snag" on the transition. Obviously, any downward angle from center would have the cartridges forward in their chambers which would, as you indicate, allow smooth cycling. I think MB was referring to the recoil plate which Uberti's don't have but he brings up the possibility of a burr that the firing pin can raise as it passes through the frame. If that is the case, filing it down will correct the problem and it more than likely won't reoccur. Mike Link to comment Share on other sites More sharing options...
Sarge Posted February 9, 2019 Author Share Posted February 9, 2019 I found a very tiny burr at the bottom of the firing pin hole. I removed the burr and shot live ammo today. Seemed fine. Reloaded with snap caps and they seemed to be fine. Have previously removed a burr from the same spot. Hoping this is not going to be a recurring issue.

Springfield Slim SASS #24733 Posted February 10, 2019 Share Posted February 10, 2019 The burr may be caused by the firing pin bottoming in the hole before the hammer bottoms out , causing the hole to become enlarged on the bottom, making the burr. Just a thought. Link to comment Share on other sites More sharing options...

Springfield Slim SASS #24733 Posted February 10, 2019 Share Posted February 10, 2019 If you are using the red plastic snap caps with the spring mounted primer, it might still happen. Link to comment Share on other sites More sharing options...
