Another M&P safety question

[treed]

I own several M&P's and have always had a question about S&W striker fired pistols. When a round is chambered and the gun is put in the "ready" condition, what percentage is the striker cocked? IOW, how much more does the trigger pull finish cocking the striker? (If any, at all)
Thanks,
Tony

Tony, S&W claims a 6.5 pound pull on most M&Ps. There are some available with a heavier pull for sale in states that require it & adding an Apex trigger kit can drop the pull to 5.5 lbs or less depending on what parts you install. You definitely have to pull the whole trigger & not just the top or bottom parts of it. It won't discharge if dropped. About the only way of discharging it beside actually pulling the trigger is to snag it on something while drawing or holstering.

I would guess the striker is 97-98% cocked. You can look at the small bump on the sear face. That bump (about 1/32 inch high) is the amount of extra sear cocking that occurs, when pulling the trigger. Smith used to call all M&Ps' double action, but in reality the striker is fully cocked and that 1/32 inch is not really necessary. They are really single actions.

The M&P has a factory sear that moves the striker back just a little bit before releasing it. If you put in an Apex sear, that little bit disappears and the striker becomes 100% cocked.

I agree with Bob, the M&P is really a single action. That little protrusion on the sear doesn't move the striker much at all. I'd say that even with the factory sear, it only moves 1% or less extra through the trigger pull.

Not all striker fired guns are the same though. The Glock moves between 1/6th and 1/8th inch with the trigger pull.

None of that matters. Both guns are cocked enough to fire, should it be possible and it's not, if the striker let go without pulling the trigger.

Thanks guys. I feel perfectly safe with the M&P's. I was just curious.

When did S&W call M&P's DA?
By definition, they are definitely SA.

IMHO, S&W added the sear protrusion in order to classify the M&P as DAO. It would then become more attractive to Law Enforcement and maybe even the Military.

I agree that by definition they are a SA gun. However, S&W used to say DA in some of the descriptions.

Thanks for hooking me up to that post. I hadn't seen it.
I found the discussion pretty interesting.
