    Light primer strikes squib round? The pencil test.

    "With the gun cleared and in a safe direction, restrain the hammer with your thumb. Pull the trigger fully, and follow the hammer forward with your thumb. Feel a bump mid-way? That’s the sear hitting the hammer’s safety notches. That can cause light primer strikes, and damage the end of the sear if not corrected"

    "The pencil test"
    1911 Pencil test

    I do not have the adjustment screw on my 1911s but the pencil test will tell If I need repair. I recently just got a light strike squib round.

    Thanks for that. I haven't run in to that, but will keep this in the reference files.

      Back when gun shows were more the norm it was common to see people popping pencils out the barrels of used guns. Most tables had a pencil or wooden dowel handy for people to use. Revolvers, 1911s, just about any used handgun with a hammer had to prove it could launch a pencil (and back then that was all of them except those dirty Glocks).

        Interesting Gimpy that is the first I saw of the pencil test when I just came across it. Mine launched just fine upon testing so I think it was a bad reload of mine?
        My UPS driver buddy just happened to stop by and I was shooting in front of the swamp shack here. I asked if he wanted to test the suppressor and luckily he said no. My God if he fired and fired another quick round with that happening as he is not into guns much? I don't care about a law suit its his eyesight I would have been horrified with.
        Youtube has a vid. of a girl shooting with her dad and blew up an M1-Garand. Squib. Damn it went up like a grenade and thank God nobody was injured.

        She is about the 5th segment in this very short squib exploding guns video. Holy sheeet not good.

          I've had 1 squib load, back when I first started reloading. It had a partial powder charge and the jacket separated from the core, with the jacket staying lodged in the barrel and the lead core flying out. It flew about 60 ft, and I saw it flying in the air. A few quick taps with a wooden dowel drove it out.

            I had a .44 Mag squib once. Man, if I had shot another round on top of that one, it could have been ugly. Wasn't even one of my reloads, either. It was "professional" reloads from the local gun shop. Pretty easy to tell when a .44 mag load feels light, at least. Popped the cylinder out and tapped the bullet back down out of the barrel and kept on shooting. But, I never bought that shop's loads again.
