SIG P365

[ap3572001]

Whats the deal with P365 ???? Are they having issues? What is a significance with build date ???

[bassplayer]

I got one for Christmas and have about 250 rounds through it. Combination of a little bit of every type of ammo I have, including reloads. No issues with the gun, it shoots like a dream, I expected more recoil with the 147 grain loads, accurate (more than I am) and conceals well. What is not to like?

But I probably have a different Sig P365 since I escaped crappyfornia! Great state when I moved there but it has gone downhill.

Seems like the issues dropped off with post-June 2018 manufacturing dates. Mostly these days it seems to be issues with the tritium.

Most issues will show up after 1000 rounds

What are the current issues to be looked for after 1000?

Main issue I have heard about is the firing pin breaks. Seems the striker system allow the the firing pin to drag across the primer. The newer ones have a different firing pin..instead of a composite. Newer ones are solid steel.

The P365 is good to go IMO. It admittedly had some teething issues. First there was barrel peening, failures to go into battery, and front sight vials breaking. Sig shut down production in March, IIRC, and changed the cuts on the barrel to eliminate peening, changed the recoil spring weight and changed night sights to their X-ray sights (they look like Night Fision sight to me).

Then, they the tips of firing pins started breaking off. That really caused an internet ***** storm, but Sig claimed to have traced that to a bad batch of firing pins. Sig said it changed its QC to correct the problem, but some claim they still have problems. Others dispute that this is an ongoing problem, and point to the fact that the guns that are having problems now, are older guns that received the defective firing pins.

It just so happens that I shot one yesterday. It has a born on date of August '18 and it has run flawlessly. It demonstrates very little primer drag, but I did notice that the primer drag increased when the gun got hot. That makes perfect sense to me.

Primer drag results because the firing pin does not withdraw before the slide starts to move and the barrel tips down. (I was also shooting a G30 yesterday, and it exhibited far more primer drag than the P365.) In the case of the P 365, Sig, which is +p rated, Sig had to deal with extremely high slide velocities (which is why the original Sig Lite night sights failed).

So what I noticed is that when the gun started to get hot, i.e., the primer drag increased. This makes sense as higher pressure rounds would tend to cause the action to unlock more rapidly giving less time for the firing pin to withdraw back into the frame.

So, you can increase the risk of mechanical breakage by running the gun hot, and I believe some of the failures are occurring because people are doing just that. This is not a service weapon. It is not designed to go to battle. It is a CCW gun, or perhaps a BUG. The problem is, unlike a typical BUG, that holds 5-7 rounds, this sucker holds 10-12, so its easy to get carried away.

And that is the beauty of the gun. Yesterday, I was shooting a G30, a S&W M&P 9mm Pro and the P365. I was shooting a 4" flapper at about 10 yards and by far the easiest and fastest to gun to make hits was not the full size 9mm, not the compact 45, but the micro 9mm! If it sounds like I'm biased, it because I am. I just love that little gun.

Would I carry one? Hell yes. The failure rate is quite low. People completely underestimate how many of these guns are out there. Sig claims a failure rate of .25%. That makes sense to me because I think they have made over 300,000 of these suckers by now. Its either that high, or Sig has a very strange serial numbering system as I've seen two born on dates separated by 10,000 in only a week's time.

Finally, FWIW, I don't believe Sig is shipping P365s with billet steel firing pins (rather they are MIM), but Lightning Strike has created a 15-4 steel firing pin that runs from the high $60's to $100. I really don't think the failure rate of the firing pins warrants a replacement though. If it gives you piece of mind, then by all means do it.

Reports of issues with ones manufactured as late as October. That issue may just be the recoil spring jumping the retainer though.

No issues with mine, shoots perfectly

My wife thinks I only have 3 guns

So slayer, what are the other 2?

Well that depends my friend... handguns, a shotguns, rifles, bows, and or muzzleloaders?...

For everyday fun, P320 X5 and or Glock 19X depends on the mood. [emoji16]

i really wanted to like that gun but when i handled one 2 weeks ago it was just too damn small for my hand - just couldn't seem to get comfortable with the hold - i have 2 Compact P320's and a P226 - i'll just have to make due with that
