M&P striker firing system?

Ah, but with a revolver, you automatically get a new round when you stroke the trigger again.

About the "sometime in the process"...if I had a dollar for everytime I've watched someone stare stupidly at a non functioning pistol -when I've just told the line to fire 4, RELOAD, and fire 4 more, I wouldn't be writing this, I'd be on a tropical beach with some naked women. You're adding options that excessively complicate matters for a large number of people.

Amen. Keep it simple and do the same clearing drill every time.

I'm only speaking from experience here, revolver or auto, I've had many rounds that took two primer hits to light off. Nothing weird about that if you ask me.

I'm not adding anything, the OP asked about the firing system on the M&P and I told him that I considered it to be a single action design, regardless of what the advertising says.

Your the one that seems to be splitting hairs here by taking the discussion in a differnt direction as I never implied that the double action feature on some pistol designs was superior, especially where training and possible defensive use of one of these weapons are concerned.

I guess in a way you kind of make my point for me though....doesn't really matter if you have an M&P or a 1911, since they are really both single actions they will be drilled/used the same. No pesky double action, double primer smacking, pull the trigger twice stuff to deal with on either of these pistols.

Racking the slide "cocks" the action. Pulling the trigger trips the sear, releasing the striker. The trigger does NO cocking of any sort in an M&P pistol.

Simply put this really is a single action design. If you happen to drop the firing pin on a bad primer the slide will have to be racked to eject the round and reset the striker, sure sounds like a single action to me.

Well now that's splitting hairs just a bit. OK just to touch on what your referring to, it's a few thousandths of an inch, at the most. That can hardly be considered "double action" in my book.

The truth is, if you drop the striker on a round and it doesn't fire in one of these pistols, you will HAVE to rack the slide and try again. Once the striker falls on the primer it will not reset without pulling the slide back, period.

From a symantecs standpoint MAYBE we can classify these guns as a double action design but in the real world their manual of arms is that of a single action design.

Using the reasoning that you just did would prove Glock to be single action and not double action, which would be silly. (The racking the slide to reset the striker being single action part).
Plus, it's related to the trigger alone when classifying.
I never go by what action the pistol is if it is striker fired, some of them are "one and a half" action (if that were a thing), so I always look at how the trigger mechanism works along with the striker.
Don't mean to revive an old thread, but the reasoning just seemed flawed to me.

EDIT: I see you are attempting to say that you see glocks & M&Ps as single action. I did not realize this at first. While I'd have to disagree with classifying the glock as a single action, I do have some trouble with calling it double action, even though the trigger does cock back the striker a bit.
I think that they ought to come out with a new term, partial double action...or something. If that catches on, I claim it.

I wasn't aware that the BATFE classified the actions of guns. Is there a link to that?

The stroke of the trigger actually does cam the sear back prior to release.

If this were what defined a double action, then all guns would be double action. Whenever you move two flat surfaces against each other in a circular motion, like all sears everywhere, one is going to be displaced a tiny amount. Even a Colt SAA, which no one would ever mistake for a double action, moves the hammer a tiny bit because of this. Fortunately, that is not what defines double or single action.

The definition of double or single action refers only to what the trigger does.

Single Action:
Pulling the trigger releases the sear.

Double Action:
Pulling the trigger first sets the sear and then releases it.

M&Ps are single action guns.

The Glock is considered a single action and a half. Because the trigger actually finishes cocking the sear, it does move the striker back more than a little. However, based on how it works, it's still a single action.

Potentially fanning the flames - if you look very closely at the geometry of the *stock* M&P sear/striker interface, as the sear rotates to release the striker, the striker is moved rearward a very small amount.

To see how, you have to look closely - there is a negative angle on the striker and a matching angle on the sear. As the sear rotates, the striker, through a microscopic camming action, moves back prior to release. It does, really. I've seen it using a cut down cap at the rear of the slide.

Just an interesting observation.

I find it amazing that this is still a point of discussion since this thread started 5 years ago.

LOL - I did not look at the start date!

Point taken!
