PS: I cleaned up the it, no grease or anything in the firing channel.

 

Depends on which Sig iteration you bought. There have been so many updates. One of the most recent updates (which affects the P365X) is the elimination of the striker reset spring. So if you pull the trigger, the striker will protrude and not reset necessarily until the slide is cycled again (locking the slide back is not a full cycle, only "half" cycle). It's easy to tell if you have the spring or not without disassembly. Just lock back the slide and look at the rear end of the slide. You should see the striker lug (silver) sitting against the firing pin safety (black). Simply press in the firing safety plunger and move the striker forward past the plunger, then let go of the striker. If the striker lug springs back on you, you have a striker reset spring. If it doesn't, you don't have one. Many Glocks do not have a striker reset spring.

The only con is that the striker may still stick out when another round is being loaded into the chamber. By design, the round with press up against the striker tip (which is rounded or slanted) and push the striker away and back into the firing pin hole where it belongs. Normally this is fine and many guns (like Glocks) function 100% properly like this however, it does induce more "stress" on the firing pin and there have been issues of firing pins breaking because of this (poor design). Sig assures us that the firing pin reset spring is unnecessary in it's most recent models.

Did SIG publicly explain why they decided to eliminate the firing pin reset spring in its most recent models, other than the obvious production cost savings?

 

It should be easy to 100% reproduce it if you don't have a firing pin reset. Ensure you're gun is safe (empty), point the gun straight down, then pull the trigger. Then lock back the slide while pointing the gun down the entire time. Even rattle/shake the gun. You might be able to hear the firing pin wiggle and you should be able to see the firing pin protruding in this manner. If you fire the gun pointing up, or shake it back, it may pull the firing pin back enough behind the firing pin safety which would make it "disappear" so to speak.

 

This is a non-issue, your pistol is functioning as designed.

 

Thanks everyone who replied. I was able to reproduce it every time when using the method @BavZHP suggested, so I'm guessing I've got the latest iteration.

Good to know my firearm is functioning as it's supposed to be.
Much appreciated for explaining it to me.

 

They may eventually say why it was eliminated. One answer may be after extensive test firing and with 1 million produced, there is no issue.

Striker fired handguns have been made for over 120 years, some of the engineering relationships are pretty well known.

The elimination of the striker reset just happened about 6 months ago, so you can't really say "1 million produced, there is no issue" but I get what you mean. Hey, I'm not saying it's a bad thing - could be an actual improvement for all I know, although I can't see why it would be - unless they changed/updated something else along with the elimination of the striker reset spring that I'm not aware of (how new strikers are made, small design improvement tweaks, etc...). Regardless, even if they only did in fact remove the striker reset - I'm sure Sigs are just as reliable and you don't have to worry about it. Many guns such as the venerable Glock 19 do not have striker reset springs.

 

so question.... should we remove the striker reset spring??? if our older guns bring them??? mine has it. born on 6/21 questions if it improves anything???

 

I wouldn’t.

 

No reset spring also means the MS (if you have one) will engage even if the gun is not cocked, which I like.

 

True, but this configuration also jams the gun such that it cannot be racked - which I dislike.

I do prefer being able to rack the first round in with the safety on. This can be done with the reset spring in place. Lock slide back - flip safety on - slingshot slide.
I ordered/installed a reset spring in my late model P365. Just my personal preference.

 

Let us revisit the slope on the firing pin tip. First, the sloped, flat spot faces up, so the incoming cartridge, arriving from the bottom, has nothing to do with it. Further, by the time the slide starts forward, to chamber that new round, the striker has been left in its mostly-cocked state, and the firing pin retracted.
The taper was introduced to reduce firing pin drag marks; as the gun recoils, the barrel assembly is dropped down, out of engagement with the slide.
The taper is to cam the firing pin back into the breech face, thus reducing marks on the primer. Whether these markings were a real issue, or simply one we have fixated on here, is another question.

Actually, the striker free-floats a bit, so when the slide moves forward after firing the striker’s static inertia should withdraw it well before contact with the next round.

 

The sear needs to pivot down against its spring to allow the foot of the striker to pass. The TS's main function is to prevent such motion of the sear.
So - when the slide is pulled back the striker foot collides with the sear vs. sliding over it as it would with TS off.
Seems one man's jam/crash/train wreck whatever is another mans lock. I can see some value in such a lock, I just don't like the mechanism.
I wonder if Sig might come around and start installing these again? They weren't removed from all variants, were they?

 

My P365MS has the reset spring and I prefer it. I can not see the striker, but I can instantly know if the striker is cocked by manipulating the safety. If the safety will go on, the striker is cocked. If the safety will not go on, the striker is not cocked. With a hammer gun it's possible to see if the gun is cocked visually, but with a striker gun there is no way to visually determine if it is cocked.

 

Yes, I have the same version and strongly prefer it this way as well for a number of reasons. That's another benefit of having the striker reset spring.

 

My strikers 365s all have the retractor spring, so I can't speak for those without it. But my striker is retracted as soon as the slide starts forward.
Glocks and 365s aren't quite the same critter. Glocks are only partially cocked by the guns action, hence the long, plasticky trigger. SIGs are nearly completely cocked, and only cammed a bit to the rear to fire.

If your P365 is equipped with the striker reset spring, you shouldn't ever see it just sticking out and staying there. As soon as it sticks out, it immediately goes back in (regardless at slide lock or not). When you pull the trigger, the striker tip only protrudes out momentarily during firing, like a short impulse and that's it, before receding. So yeah, of course you will not see it just sticking out... and a thing for you to think about is this: just because your striker tip is receded and can't be seen, does not mean that your striker is cocked. I think you are believing that they are in fact synonymous, but you're wrong there. It's an important distinction.

 

BavZHP, read what I said. I said retracted, not 'cocked'.
The preload (cocking?) is completed by the forward motion of the slide.
As noted, my optic equipped 365 slide is a recent purchase, and the optics are a relatively new thing. When was the retracting spring deleted?
I've some older, spare firing pin units in the spares box; have to take a longer look at those.

Yeah, I know you said "retracted," but you were also using it the synonymously as "cocked" - here's your word choice in complete context "When the slide starts forward, the firing pin has already been captured by the sear. The firing pin will be fully retracted as the slide starts forward."

Anyways, all besides the point now. I realize you now know when the sear is being truly cocked. That was my goal, just to educate and understand.

 

I believe the retracting spring was deleted in June or July of 2021. If you have the beveled firing pin, you do not have the retracting spring.

 

Was this change made to guns with MS, or only to those without?

 

Do we have confirmation that the newer FPs are in fact not beveled? We're talking about the sloping flat on the upper side of the firing pin.
That bevel was a BFD at one point.

If I got a newer MS model that didn’t have the reset spring I’d be looking to add it. My 2019 model has it and I’ve experimented taking it out and definitely prefer the way the safety functions with it. I’d also prefer the striker wasn’t unnecessarily protruding even if it’s a non issue from an engineering perspective.

 

I've submitted an inquiry to Sig support staff on this topic. If they respond I'll share it here. I asked them about the elimination of the spring reset and if it's ok to add/remove one.

 

Ok my XL was produced on 10/11/21 and is a MS. My firing pin protrudes like the OP. My slide will not move if the pistol is not cocked and the MS is activated. The slide will move if the pistol is cocked and the safety is on. So I guess mine does not have the reset.

I just bought my 365 xmacro yesterday. Sometimes my firing pin protrudes when the slide is locked back, and sometimes it doesn't.

When I perform the check from post three, my my striker does not spring back, which would indicate I don't have the reset spring.

Upon playing with it some more, it appears that most of the time my striker is stuck halfway back and is on top of the safety plunger. Putting it another way, most of the time the safety plunger never gets to reset because the striker is parked on top of it. It's sitting right on top and I can manually push it backward for a full reset, or forward to have the striker protrude.

I just got the gun, and have only put around 80 round through it, but it functioned perfectly over that short run. Perhaps having the striker riding on top of the depressed safety plunger isn't that unusual (or doesn't matter) with the slide locked back? I'm guessing that when the slide comes forward the striker is fully-back and the safety plunger is in the extended position, blocking the forward path of the striker.

 

I bought my first Sig (365x Romeo) and passed 450 rounds w/o any issue. Noticed the protruding striker tip and was afraid of misfiring. Glad what you have discussed. Here’s my investigation. There’re 3 positions of the striker tip: 1) protruding in photo 1; 2) resting in photo 2; 3) corked or ready to fire in photo 3. I removed the barrel and spring to take the photos. The striker sometimes stayed protruding after the trigger pull until the slide was cycled back and forward where the striker blocker was engaged. At that point, the tip went in but could still be seen inside the breach hole in photo 2. When the slide came to the firing position, the striker was loaded and the tip could no longer been seen in photo 3. I pull the trigger slightly and could feel the striker spring tension.
The confusing part that protrusion happens randomly. I guess this isn’t important as long as the tip goes in before the slide completes cycling.
I checked my Glock 17. The striker tip is sticking out but can be pushed inside. The striker is ready when the slide completes cycling. That gun went through at least 5,000 rounds w/o any issue.
I’ll go to the range and be very careful until I’m fully comfortable.
BTW, my striker has no reset spring. I thought I dropped it until I saw SigGuy’s videohttps://youtu.be/-ZcbWfin1gA

 

 

Just to give an update: fired 300 rounds at the range. No single misfire occurred when the slide closed. I'm not going to worry about the protruding striker tip.
