    Revolver w/bobbed hammer,should you test fire after its done?

    I just picked up my colt cobra from my gunsmith after he bobbed the hammer for me. My question is should I test fire the gun before carrying it again? I ask as I've heard that sometimes a bobbed hammer doesn't retain enough mass to ensure reliable ignition. My gunsmith said if the gun is in proper mechanical condition and working(which my gun is) order this isn't an issue,is this the case?

    By the way my smith has been doing this 30 years and he did a great job to,so am I good to go here guys?

    Yes you absolutely should test it out before relying on it. If it fails to fire though it won't be because the hammer was bobbed. Lowering the mass of the hammer does not reduce the energy it imparts to the firing pin. That's a matter of spring power. I have bobbed many hammers and unless the springs are changed it makes no difference. So unless your smith changed the springs you should be GTG. But verify as Reagan liked to say.

    I know on the old S&W revolvers with the firing pin fixed to the hammer, you can cut too much mass off and get some mis-fires. Definately verify function before relying on the gun after ANY work is done it.

    drail no springs were changed and I'v shot this gun many times before the hammer was bobbed this week. So are you saying I'm good to go given the gun has been shot and worked fine prior to this modification being done and no springs were changed,theres no reason it shouldn't work

    I would say that you are still good to go - with only the hammer bobbed and nothing else changed on your revolver.
    Especially since the hammer springs on Colt wheelguns are slightly heavier poundage than they need to be to insure reliable ignition anyway.

    I'd trust your long time gun-smith on this one.

    Ditto what QKShooter said, plus the gunsmith may have tested the hammer strike for reliability.

    I'd test fire any SD gun after having any work done on it. I just can't think of any reason not to......

    When in doubt........test it. You don't sound sure, although it is very likely going to to BANG just like it should, no reason to leave a doubt hanging.
    Be prepared

    test fire the gun, that way you feel good. the bobbing of the hammer with not effect anything. i have put in bobbed hammers in all of my j-frames. at one time you could buy a factory bobbed hammer.

    I agree, but wouldn't you want to give her a couple of 'blasts' just to see???????

    Thanks guys I think I'll shoot her just for the heck of it,although I'm 99% sure theres no reason it won't go bang. Any reason to shoot is a good one I guess,as a side note I learned my cobra uses a leaf spring and not a coil spring i thought that was cool.

    Oh...absolutely.
    My only point being that a lightened/bobbed hammer is only ever problematic coupled with an overly light hammer spring. Since he is staying with the original hammer spring weight he would be good to go.
    I think the hammer spring on a Colt Cobra wheelie can be reduced down past 9# but, I sure would not do that in combination with bobbed hammer.

    Hey guys I juat hit the range and put a few cylinders through my cobra. I used and assortment of federal,winchester and magtech ammo. All went bang with no issues and the primers all had consistant,deep indentations from the firing pin. I would have shot more but I'm on a short lunch today at work.

    So I think all is well being this gun has had a lot of rounds through it. I gotta say I'm really impressed my smith did a really nice job bobbing the hammer on this gun. Its looks like it came from colt like this. I'll post some pics when I get home today.

    I'd trust the smith, but whats wrong with just making sure? Go ahead, set your mind at ease.
