striker safety question?

[sk8804]

i dont know why i never thought about this before, but say you have an m&p .40 and ccwd with a rnd in the pipe, what would happen if the striker slipped somehow? i always thought there was a firing pin block that didnt move untill the trigger was pressed. So, would it fire or not?

The firing pin block would need to be pushed up and out of the way for the firing pin to go forward. Literally impossible unless the trigger got pulled.

In a striker type handgun like a MP or Glock... you have to work the trigger to push the striker into position for it to drop. SO... with a round int he chamber, it's pretty safe unless pressure is applied to the trigger, disengaging the trigger safety and continuing with enough pressure to overcome the spring pressure of the striker.

Not sure if the striker can actually "slip" per-say.

i figured there had to be some kind of safety. Just didnt know what would happen if the sear blade that holds the pin back sheared off for some crazy reason. Lol my mind was wandering bad.

"No chambered rounds in striker fired autos for carry" used to be the rule, and still is for many older guns.
With the introduction of firing pin blocks in most newer quality semiautos, carry with a chambered round is safe to do.

in order for the striker to go forward on an M&P, the trigger is pulled which moves the firing pin block out of the way, and then the sear, which retains the striker to the rear via the striker's nose, is moved down out of the way.

if the striker's nose were to break, or if the sear mechanism were to fail, the striker would move forward and contact the firing pin block.

in order for the M&P to fire due to mechanical failure, the firing pin block mechanism would have to either stick or break, as would either the sear or striker nose.

a glock adds to the mix that even if the sear/nose and FPB were to fail, the striker is not under enough tension to reliably ignite a primer unless the cocking cycle is completed by pressing the trigger to the rear.

Cool. Good to know. Thanks guys.

How old are we talking. 5 years, 10, years, 20 years.

There are still lots of striker fired guns without FPBs being made today.
The whole Ring Of Fire auto family: Jennings, Raven, Davis, Cobra .32 / .380 / 9mm.
This same striker design was used on most Euro autos, too, of which import ended in 1986.
You really need to look at each guns design carefully to know for sure.
FPBs got real popular right after liabilty law suits raised their heads.
Colt's Series 80 design (1983) added a FPB to the venerable 1911 due largely to the legal climate at that time.
Glock came to the USA with a striker-fired pistol with a FPB about 1984-ish?
So by modern I mean mid-1980s and later designs, I guess.

i am very proficient with gun safety and know how to shoot, i thought there had to be a block for an accidental shear or slip of the pin, but never researched it before. lol
