Striker spring question

[ou1954]

Striker Block

The gun has a striker block.

Remove your slide and try to push the striker forward. You can't. Unless you pull the trigger and push the striker block up, the striker can not move forward enough to strike a primer.

The striker can not move forward under inertia alone and strike a primer.

Yes, indeed. The striker blocker is lifted by a lobe on the trigger bar. And yes, the SD series was drop tested in order to meet CA and other state requirements, but the question is: "Why did S&W put than meaningless spring into their guns?" It wasn't to save money and it wasn't to help pull the striker forward.

Why then add another part to a price-point gun?

I have previously suggested that this group, as a whole, try to see whether the addition of that spring relates to approval by any of the more restrictive states. I have posted a summary of the CA test requirements for reliability and safety.

I don't know about other states but some folks here must know when various changes were made.

I no longer live in California, having moved from there several years ago. I am open/closed carry licensed in this state but our gun lives at home except when it is able to go to a range.

One cannot say what happens when a gun is dropped. If you have time, look at some videos on lock picking and you will see that inertia plays a major part of some picking techniques. Could be that inertia comes into play when a gun is dropped.

SD9VE factory striker spring

Got the new striker assembly and It does have the second spring, I haven't had time to do the measuring. I ended up using the old plastic sleeve with the slot as the striker pin would hang when pushed in by hand and I traced it down to that sleeve, it was just too tight a fit.
Took it to the range and didn't have any fail to fire with 4 mags, I did have a fail to eject

FWIW, just a note of reference:

I just bought a new 9mm Shield. When I took it apart to give it a good cleaning, it has the same exact spring setup. The big striker spring and then a little one pushing back against it from the other side of the plastic tube.

It really doesn't make sense. I can't see how that thin little spring can overpower the bigger striker spring under any circumstance.

Kind of funny , got to the range this weekend and I wanted to make sure I did't have any more misfires after installing the new striker. Shot a round and misfire ! Darn , pulled slide back 2 times , no bang, finally ejected the round and it was one of my snapcaps !

The rest of the magazines went bang just like they should.
