It's a -1, which shows more carrying than turn ring indicates. Having two problems:

1- Misfires 2/3 times from light hits in DA, single action is fine. Replaced mainsppring TWICE ! Cylinder gap is 0.008. I can fire SA on FTF rounds and the round fires. Looking at the cylinder ring it appears to have not been fired a whole lot and firing pin looks good. VERY little end shake.

2- After firing 36 rounds or so empties won't eject unless I carefully tap ejector rod on the bench ( sometimes pretty hard ! ).....I've cleaned it real well numerous times and used my Dremel with Simichrome polish to polish chambers thinking there may be pitting I can't see.

ALL SUGGESTIONS Appreciated !

Thanks-Dan

I've had issues with mine also.....you might try some different brands of ammo to see which ones function best. Also check to see that the area beneath the extractor is super clean. Any dirt or powder residue under there spells trouble. Check to see that the extractor alignment pins are in place. If one comes out, or is not properly seated it can prevent the extractor from going back into it's resting location properly. And......make sure you're seating the live ammo all the way into the cylinder hole when you load the gun. These are the things that come to mind right off the bat. Perhaps other members will have additional ideas.

Is it possible its been dry fired a lot and the firing pin is peened (which might explain the ftf) and the corresponding lip of the chambers near the extractor are nicked (which could explain the difficulty ejecting)?

this makes more sense to me than thing I have heard to date.

Originally posted by Hondo44 - thanks Jim - hope you don't mind.

[I]I bought a new 18-4 and had the same problem. So I loaded and shot five leaving one chamber empty. The cases still ejected hard. Then I loaded five again and left a different chamber empty and they still ejected hard. When I did that the third time, the cases almost fell out. So I marked the chamber I left empty that time and didn't use it again. After checking all six chambers the cases all fell out. I saved the case from the sticking chamber. When I got home I used my 10X glasses and examined that case and the offending chamber.

There was a tiny dimple in the case right near the rim. When I examined the chamber, sure enough there was a burr from cutting the rim recess folded over into the chamber and blued over so I couldn't see it w/o the 10X glasses. I sliced it off with an exacto knife. Next time at the range the problem was solved! I was surprised that just one sticking chamber could make it so hard to eject.

If you still have the gun and haven't found the problem yet, you may want to try that process of elimination before you take it somewhere and see if it's only one or two chambers causing the problem.

Good luck and all the best,

Tried above....still FTFs. Dang.
More info?????

Thanks
Dan

One other thing you might check on double action is something my S&W factory instructors called "wink". When the trigger is pulled back in double action and the hammer goes forward, the "rebound seat" on the bottom of the hammer should come down to rest in front of the "hammer seat" on the rebound slide. To check, make sure the gun is empty, pull the trigger and hold the trigger all the way back. The hammer should now be in battery fully in the frame. While holding the trigger back, put your thumb on the back of the hammer spur and hold the hammer forcefully forward. While holding this pressure on the hammer, release the trigger slightly to see if you can feel a small movement in the trigger back and forth. This movement shows clearance between the raised seat on the bottom of the hammer and the seat on the top of the rebound. If this relationship is not properly fitted, the hammer can go forward in double action and strike the front edge of the step on the rebound.....causing light hammer strikes.
This malfunction frequently manifests itself during double action, particularly when the user fails to pull the trigger fully back.....or because the parts weren't fitted properly to begin with. Just another possible explanation for your light primer strikes.
