Occasionally on my Smith & Wesson 642 when doing some dry fire practice the cylinder occasionally does not rotate after I pull the trigger. No dirt or powder buildup, the cylinder spins freely when the gate is open. At times it works just fine but then at times it just stops turnin I haven't tried this yet with live fire just wondered what it could be??

"The gate is open"??????? How about a picture of whatever you think "the gate" is?

Uh, OK, are you talking about having the cylinder swung out of the frame?

The cylinder is supposed to rotate WHILE you're pulling the trigger. It's NOT supposed to be able to rotate with the trigger either fully forward or back. You might want to return that one to S&W for service if it's not.

Is it possible that someone opened it up, and in the process of removing the trigger, pulled the hand too far back to clear the frame, thereby causing the torsion spring that keeps forward pressure on the hand to slip from behind the stud in the trigger, resulting in the hand having no forward spring tension to maintain engagement with the ratchet when the trigger is pulled?

This can be checked without taking the revolver apart by swinging out the cylinder and putting rearward pressure on the hand through its window in the frame and after pushing it back just a little (with the revolver pointing straight up), checking to see if the hand springs forward under spring pressure. If there is no spring pressure forcing the hand forward, then this is the problem.

If this is not the problem, then the revolver should go back to S&W.
 
You could be short stroking it, which is not allowing the trigger to move all the way back forward. If not that, it is a hand problem, either the spring as mentioned above or it is binding in the window. I would give it a good cleaning before anything else

I've found that short stroking the trigger results in the cylinder turning while the hammer doesn't move. It's kind of shocking the first time it happens.
 
Make sure the sideplate screws are PROPERLY tight, not overly so. This corrected this problem on my 442PC. Don't know why, just did. Never been really happy with my Chattanooga Arms 442PCs and won't carry them.

My 2nd place 'vote' is for short-stroking. Your problem occurs in dry fire. See what happens (or doesn't) with factory ammo.
