Striker spring question

[Dr Denby]

Does anyone know for sure if this striker assembly from midway fits the sd9ve ? If so thinking I might get one as a spare seeing as how I've heard that S&W won't sell them to consumers

Smith & Wesson Striker Assembly S&W M&P M&P Compact 9mm Luger 357 Sig

It does not look like it star.

The SDVE striker slides thru a long groove in that white plastic sheath.

The one pictured does not look like there is a groove cut into the white plastic. It looks like the striker sticks up thru a "hole" in the sheath, rather than sliding along a groove.

By the way... the person I spoke with said you can buy parts for the SDVE, I specifically gave that model and he said yes.

He said parts can take 2 to 3 weeks, but you can buy parts.

I called S&W some time ago (over a year ago) and asked about buying a RSA and a striker assembly. (I like to have some spare parts on hand.) The person I spoke to said they would send me a RSA for free, since it was a normal wear/replace item, but that they wouldn't sell a striker assembly. I asked why, and he said that if there was a problem with the striker, they wanted to take a look at it and see what was going on, and fix it, since it shouldn't wear out in normal use.

 

[Dr Denby]

Hmm

That seems like an odd thing for them to say. I mean this relatively thin point of metal is repeatedly slamming against metal. It may take a while, but logic says it WILL break.

I did not ask about the striker assembly specifically. I only asked if one can buy SDVE parts. They are sending me a striker spring, so you can at least order that.

It may have been the person I was speaking to. In the past, I've gotten different answers from different reps. For example, a while back, I wanted to buy some extended magazine base plates for my M&P9c, and one rep told me they couldn't sell me one. I called back, and the different rep said they would send me one for free (and they did.)

I took the SD9VE striker all the way apart as I wanted to measure the striker pin protrusion and I DO have the second small spring.

I have about .050 " of pin protrusion when the striker is pushed all the way forward with the striker block depressed. Does that measure up to anyone else's SD ?

striker pin protrusion

With calipers I measured the distance between B and C with the striker pin flush with "A" , pushed striker pin all the way ahead(after depressing the striker block) and measured between B and C again....came up with about .050 " of movement

Added spring

That's crazy.

It sounds like it was added late in the design to pass some safety test and they never updated their diagrams.

Could a spring have been added to enable that model to pass the drop test required by some states?

 

[star1]

It is a pretty light duty spring, I wonder if it is to just help with alignment . On another note I called S&W about my striker and they are sending me one free of charge!

So just to clarify the placement of the spring in question:

You guys are saying that the smaller spring goes on the striker first, then the white plastic sheath, then the large spring (the one that Apex has in their kit), then the white plastic keepers?

 

[Dr Denby]

Awesome, Norm. Good deal.

When you receive it, if you could answer your own question about how far the striker tip is supposed to come out, I would like to know. And if you feel like checking, see if it has that silly second spring. It would be very interesting if it doesn't

Yes, Dmk, you are correct. And the spring appears quite useless with no noticeable function. It is small, thin, only a few coils that are spread well apart.

I don't see how it would provide any type of "safety". I wonder though, perhaps it was added just to say that there was a spring there. "hey idiotic regulations people, we added a second striker spring".. without mentioning that it is useless.

[star1]

That sounds about right , it is a very light , weak spring . Now I wish I had taken a picture as I pulled it apart

Here is a picture of the springs

 

[dmk0210]

Thanks for the picture Norm!

 

[star1]

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
Norm

 

[Dr Denby]

Great to hear that that solved your FTF troubles, Norm.

The fail to eject is worrying, though if it happens again.

Gee, you got it in 4 days and you called them a day later than I did !

I have not got the spring yet and they said it could be 2-3 weeks!!

I am thinking they might not have liked my questioning the part and my disbelief that they did not have any idea why it was there.

Striker spring

Thanks for the replies guys.

I was assuming that in went in the channel (towards the chamber) first before the striker went in to push the striker towards the rear and act as resistance to the gun dropping on the muzzle.

I tried Google searching but can't find a picture or diagram showing the smaller spring anywhere.

I still suggest it is there to insure that the weapon passes the drop test, California in particular. I've posted that test before so won't re-post it here.

Although S&W doesn't condone users disassembling strikers, it seems that most folks on this forum have had theirs out. Maybe enough folks with older guns can determine a manufacturing date when that second spring appeared and relate it to the CA laws. (Microstamping is still part of the CA law but is not being enforced pending court proceedings.)

It looks like all S&W pistols and revolvers will fall off the CA roster on 1/1/2016.

I had the notion from prior trips to the various CA sites that when guns fall off the roster they have to be completely re-tested. Must not be accurate, however.

ADDED COMMENT - - - - - - -

I just noticed that Glock handguns fall off the CA roster on 1/1/2017. Also, the CA roster includes these comments, in RED.

No Generation 4 Glock handguns have been approved as of: Tuesday, November 24, 2015

No Glock handguns made in the USA have been approved as of: Tuesday, November 24, 2015

I have the Sigma SW9ve and it has the 2nd spring also, just had mine out today when I put the original spring back in and took out the APEX spring...too many light strikes. Went back to the range and it worked perfectly

I did the same thing. I experienced a few light strikes with no ignition with my SD40VE and the Apex striker spring. Every round fired on a second strike (these were premium HSTs and Gold Dots too).

That prompted me to swap back to the OEM striker spring on the SD40 and I didn't even install the Apex striker spring in the 9mm gun. It wasn't worth the risk to me.

If you take that small spring out, just be careful to not drop your gun when it's loaded!

If you do drop it when it's loaded be sure it doesn't fall barrel down on your foot.

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.
