The pencil test...

OK, so the pencil test goes something like this.

Stick a pencil down the barrel of your UNLOADED gun that is cocked while pointed up. Pull the trigger, and it shuld launch the pencil.

Except most M&P owners seem to not even clear the barrel, wheras other guns launch it a foot or more in the air. Is there something wrong with this?

Well first off, my M&P is on par here. However, having a several boxes of unsharpened ticonderoga #2s at my disposal, I played around with the M&P and other guns and noticed some iteresting things.

1) the M&P will shoot a pencil plenty high is you put the unsharpened end in first.

2) the M&P actually seems to put holes in the eraser

3) my two 1911s and baby eagle do not put holes in the eraser.

My conclusion is that I think the M&P is delivering plenty of oomph, but theres something weird about it.

Feel free to chime in with your theories and observations.

I agree, I test the M&P before and after trigger jobs with a nylon rod and they all put marks in my ceiling. If you use the eraser end of a pencil it is kind of a dud.

I am thinking it has to do with the shape of the striker it is kind of cone shaped a tad bit smaller on the very end than most 1911s and that allows it to penetrate the eraser.

I figure if it has enough energy to bounce the punch off my celing it ought to be enough to light any primer.
