Default Model 19, gets stuck while dryfireing

The model 19-3 I plan to use for IDPA (see separate thread) is "jamming" while dryfiring.
I practice dryfire by double tapping as fast as I can pull the trigger and hold steady. This gun will jam when attempting to pull the trigger. The trigger goes back 1/4 of the way and the cylinder refuses to advance and the trigger will not go further. If I let up on the trigger and pull again, it will fire.
I've done a thorough revolver check for timing and cylinder movement and it looks great to me, however I'm no expert.
It will jam about every 12-15 trigger pulls, but I'm not sure there is any consistency that I can see. I've never had it do this while actually firing ammo, just dry fire. I probably am dryfiring faster than I actually shoot. Do you know what's wrong and how to get this fixed?
Thanks,
John

It sounds like you are short stroking the return. Let the trigger come back forward all the way before pulling it again.

Yep. You have to move your finger both directions when shooting fast. You can't just ride the trigger back forward.

You are probably short stroking as stated. Normally shooters do that because they are trying to pull the second shot off too fast. With live ammunition it doesn't happen because the recoil causes you to shoot slower.

The short-stroking advice is probably correct, especially if you have modified or chaged the rebound slide spring to a lighter spring.

Another possibility is the stop is catching, or not being pulled down properly and in time by the trigger hook.......or it is coming back up too fast. (skipping)

If there is inadequate material on the trigger hook or the stop bevel due to wear or improper intervention or fitting, the stop can be "late", that is, it's not being pulled down out of the stop slot in the cylinder soon enough, and locks the action.

short stroking sounds like the top contender

You can test this by slowly allowing the trigger to move forward after a double action stroke, to the point just before it returns all the way forward. There is a point just before the trigger returns all the way forward that will bind the gun when pulling the trigger rearward again. Sometimes it takes a few tries to find that spot as it is a rather narrow window where this can occur. It is worse on some guns than others.

Thanks for the advice guys! Short stroking it is. Apparently my trigger finger gets tires after a time and I short stroke it. No wonder it doesn't happen during live fire. Nightowl, I did what you suggested and can plainly see the issue. I'm glad to see that it was the operator not the gun!
Thanks guys you are the best!
John

Ed McGivern in his book, "Fast and Fancy Revolver Shooting" stated something about a deliberate trigger return was the secret to fast double-action work.
