One of the nice things about the 1911 sear is that it's more or less pivoted in the more or less center so that more or less however you drop it, it won't rotate out of engagement.  More or less.

I can't believe it was necessary for him to 'splain that the rounds only fired the primer, with no powder or bullet in the empty case.  Anyone dumb enough to make that kind of comment about the "danger" of "having a gun go off" in that testing should not be commenting at all.

The same idiots that freak out if your finger touches the trigger.

[T.O.M.]

How is it that so many of these internet gun gurus have the money to buy guns just to beat them up?  I have to save up for months to buy another firearm, and I'm damn sure not intentionally dropping one of mine...

One of the comments I have heard since this started as that the series 80 safety was added at least in part to prevent firing when dropped.  Is that what you are referring to when you mention the 1911 sear?

^ No.  The little guy in the middle:



My untested observation of this occured while I was thinking about why the striker of that other gun I described tended to slip off the sear when dropped.  In other words, just from examining the mechanics of the 1911 sear and hammer relationships.

This is not to say the milspec 1911 can't go off if subjected to high gees in any given direction, but this particular part is less likely to pivot off the full-cock hammer notch because of its inertia.  It's sort of "balanced" on the hole in the middle.

Any gee forces* which would tend to rotate its top part clockwise off the hammer's sear notch are counterbalanced by the same gee forces tending to rotate the sear counter-clockwise by the mass below the pivot point in the middle.

However, I can't speak to finely-tuned commercial 1911s in this respect.

The Series 80 stuff is a firing pin block, it doesn't affect the sear. In the 1911, tripping the sear releases the hammer, which then whacks the firing pin. What the firing pin block does is ensure that, even if the sear gets tripped, if the trigger hasn't been pulled the firing pin can't move far enough to make contact with the primer.

Even without the firing pin block, the 1911 still has multiple safeties -- the thumb safety, and the grip safety. About the only way a 1911 can fire in a drop is if dropped directly on the muzzle. In that orientation, the firing pin still has to overcome the firing pin spring, and the use of a lightweight firing pin and/or an extra-power firing pin spring pretty well eliminates even that possibility.

Benny doesn't need a trebuchet.

Our Boy Scout Troop has a trebuchet.  We normally fling various sports balls, but it could easily accommodate a pistol, possibly even a sub-gun....

I got this email today from Century.  I had to laugh a little at the language.  If you drop our pistol a bunch or otherwise destructively test it, the warranty is void.
