Concern about revolver "jamming"

    I have a Colt double action revolver. I bought it new unfired. I have had ZERO problems with it except this:

    Two separate times when I was aiming, I pulled the trigger back very slowly. For whatever reasons, I eased off the trigger, or somehow backed off the pressure, and then increased the pressure and attempted to fire. These two times that it happened, the cylinder basically locked up. To cure the problem, you just have to hit the cylinder release, let the cylinder fall out and then close it.

    I have tried to recreate this but cant do it. I am trying to get it to screw up, but now I cant.

    Im not really worried about it, cause I know the times it has happened was when I was doing screwy stuff with the trigger, and in a defensive situation would never shoot like that. None the less, has anyone heard of this before?

    The revolver is clean and well maintained. There are no modifications or action jobs done to it.

    Sounds kinda like the feller that went to the Doc and said. "Doc, it hurts when I do this."
    Doc sez, "Well, don't do that!":evil::D

    :) Very true. Probably the best advice there is. :)

    My first inclination is a detailed strip, thorough cleaning and inspection, lube and reassembly. You may turn up something broken, loose, or worn, or perhaps more likely in the case of an intermittent problem, fouled. Not knowing Colts at all, I would go heavy on the research first to determine if I should tackle the matter or haul it into a 'smith. Although I wish they were more thoroughly indexed, I am glad I own the Jerry Kuhnhausen books for those guns I own. Note that there are two volumes for Colt double action revolvers, each covering different models. I prefer to buy such things at my local gun shop if I can.

    I would sugest you strip it down and clean the trigger group.

    got this 586 that did the same thing back when I first got it. Took it back tothe shop where I purchased it and they had it for a week before it was "ready". Took it out that weekend and it did the same thing! Went back and explained to another gunsmith what was going on. He cocked the hammer back a few times and commented, "I know what's wrong with it"! Went to his work station and about 15,20 minutes at the max, handed it back to me and said, "fixed it".That was in the mid 80's and it would be hard to even guess how many thousands of rounds that gun has sent down range, without ONE glitch. I do not own one auto that I can say the same thing about. Place, Tucson, Az Shop, Jenson's

    I am not sure what was wrong with that S&W but I think I know what is wrong with the Colt. Trouble is that it would be almost impossible to describe the problem or tell how to fix it to someone who is not a Colt expert. I think Colt will still work on those guns, so I would give them a call. If they can't help, come back and we'll try to work something out.

    Try some snap caps for your new unfired revolver..500 DA cycles might help loosen-up the action..do not lubricate until you have gone thru 500 cycles..factory lube will suffice,,in fact a little dirt will wear-off the high spots from the machining processes used to produce the parts. After that a good cleaning and lube is necessary..anyway Iggy is correct anything mechanical doesn't like to be put in Reverse halfway thru its designed cycle..

    Thanks gentlemen. This gives me some possible routes to take. Im going to think about sending it to Colt, and in the meantime, maybe Ill try the snap caps and see if I can figure out when its happening (if I can get it to happen again) so I can accurately describe what is going on, and at the same time maybe smooth out the action. It literally has not had very many rounds through it, and is, in my opinion, barely broken in. I wouldn't think it would be gummed up yet.

    Thats my one concern with sending it to Colt. If its just because Im the one causing it to act screwy, then maybe its my fault and it is to be expected...

    Is this a recent production Colt or an older gun?

    There is a specific mention of this in the SF-VI/Magnum carry manual.

    You don't mention which model you have. Colt made several different DA designs over the years. What gun do you have?

    This is a Colt detective special, I believe 90's era. I will check the manual to see if this is mentioned...

    Checked the manual, nothing mentioned on this one. This is not a SF-IV, but I wonder if it is the same deal? If you have the information from the manual, would love to hear it.

    Maybe you are, in effect, trying a second pull without letting the trigger reset..."or somehow backed off the pressure"...somehow as in letting the trigger go forward a bit?

    It sounds like to me you are "short stroking" the gun. Colts Det Spec have a very low spring tension return spring. It is part of the main spring. I often short stroke mine and that is why I don't CCW with it. Just my own feelings on it.
    The return spring may be weak.
    If you decide to take it a part, pay attention to how it comes a part, so you can put it back together again. The old Colts have more **** in them than a Christmas turkey. :)

    Timing on a revolver can be tricky - new ones and old ones are mis-timed, very common. If you're not a tinkerer, a gunsmith is your best bet. If you are, a supply of parts like hands, hammers, and triggers in different thicknesses etc. and lots of patience are required as it's easy to ruin these. You can eventually get really good at tuning - I tune mine and I'd say I'm as good as any smith. I also have a box of (somewhat expensive) ruined parts I made while learning.

    Clean and lube is always the place to start, if that doesn't work get the right set of screwdrivers and disassemble. Clean gunk off. Look for rust and carefully POLISH (do not grind or remove any metal - hand polish using 1600 grit cloth or finer), staying away from the ratchet, hand ends, etc.

    If it's still off you may need some parts, like thicker hands, hammers, trigger, what have you. and some skill and tools to fit them. This is where it gets tricky and expensive.

    If you don't know how to take it apart ~ don't home-smith it. You can mess the side plate up if you don't remove it properly. It comes out with vibration not forcing it.

    Don't get 'er started then back out or she may very well lock up on ya'. That's bad form anyway, dude.:evil:

    As you pull the trigger, the hammer will go back and the cylinder will begin to turn to the next chamber. If you then decide not to finish pulling the trigger then the hammer will ease back down but the cylinder will stay inbetween chambers and not be in a stop notch. Try to either spin the cylinder in either direction without applying much pressure at all. If it is indeed stuck then you may have to open her up. You aren't allowing the timing to get the full motion.
