I was looking at you tube videos and found my Shield does this as well.
Is it an issue or functioning properly?
Thanks

Point it, shoot it defend you and yours,,
As long as its doing this with no problems. . You are good to go..

My Shield 9mm does the same thing.
I found it while I was cleaning and messing with it when I first bought it.
I called S&W and they gave me the address of a location local to me where a S&W armorer worked.
I took it to him and he disassembled the gun and checked it out, he said it wouldn't hurt anything.
He fired a few rounds to check the dimple the firing pin made on the primer, it looked good, he handed me my gun and said it won't give me any trouble, shoot it and don't worry about it. So I have been shooting it and I haven't had a bit of trouble with it.

I don't see a problem

I am not so concerned with it shooting properly as I am if the block isn't functioning correctly and it shoots when it is not supposed to.
I am new to guns but shouldn't the striker block stop the striker until the trigger is pulled?

I'm not sure what the problem is supposed to be here? If I understand how the Shield works, when the slide is racked to load a live cartridge, the striker will be pulled back away from the striker block which then engages so that it blocks the striker should it somehow be jarred loose without the trigger being pulled. The gun is now 'cocked' and ready to fire. When you pull the trigger the striker block is pushed up out of the way by the trigger mechanism and the striker is released and can hit the live round's primer. The only way I can see that you would have the striker in the position shown by the video along with a 'live' round in the chamber is if it didn't go bang the first time the trigger was pulled. And at that point, the striker is so far forward that I doubt dropping the gun on it's muzzle would generate enough force to hit the primer very hard if at all.

I'm sure plenty of folks will let me know if I have this figured wrong.

It's not a problem. Carry on.

Like the vid shows (and PirateJim said), You need to rack the slide to load a round. When you rack the slide, the striker will catch the sear and allow the block to "reset".

I test this when I disassemble and clean all my pistols with striker/FP blocks.

This is so wrong. Not an issue.
Each time the slide is racked back whether by hand or during a shot, the striker lever gets pulled back and resets the striker block. If this guy understood that, it would not be a concern.

It would be like a guy looking at the sear actuated by the trigger and sees that when the trigger is held back, the sear won't catch the striker and the gun will fire full auto not realizing that the trigger bar loop gets pushed out of the way by the slide and can't actuate the sear until it is reset by releasing the trigger.

A little bit of knowledge is dangerous.

And someone with only a little bit of knowledge, along with a Youtube Account can disseminate a LOT of bad/wrong/confusing/incorrect information to a lot of people who know even less, very quickly.
At least the OP asked about it.

Ianwe, congratulations on your new pistol. You were concerned by something that you don't have experience with & came to ask for advice, smart move on your part . That is the basic premise of this forum . Rpking had the same issue & handled it well. It's nice when we have help w the learning process. I checked my FS M&Ps & they will reset every time so it may just be a Shield thing, or it may mean that the slide internals need to be cleaned. At any rate you should shoot it and enjoy yourself. Have fun & be safe.

Basically manually disengaging the striker block to allow the striker to move forward.

When you push the striker forward, there is not much spring tension that pushes the striker to the rear... So the striker is still forward enough to be within the area of the striker block. The striker block can not reset due to the striker still being in the way.

It's completely normal and several striker pistols do this.

Guns are such an interesting lifestyle to get into. Everyone is new at some point. And you can learn something new every day.
Thanks for the help.

OP, it is considered normal for the M&P design according to my long ago call to S&W customer service. I can see why it would be mentioned as a concern because that behavior is not usually seen in other striker-fired designs. With that said, when testing the proper movement of the striker block safety, it is important to first pull back the striker so that it is not in contact with the block. That should also be done when assessing the grittiness of the striker block (while pushing the block in at the slight angle the trigger bar engages it).
