Sig cutting corners with new P320s to keep up with production?

Sig cutting corners with new P320s to keep up with production?

I decided to wipe down my new P320 and thought the FDE color was a little different than my other 320....true enough it does seem a little lighter. Oh well

What caught my eye next was this



Slide on the left is my older P320 with a build date of January 2016 and the other one is my new P320 with a build date of February 2017

The new one looks like it missed a couple of stations on the assembly line??

Even the stainless piece of metal is different

Old



New




See on the old one it is lower and flat for a bit before angling down? On the new one it is taller and just a straight angle down?




Can anyone who just got a P320 and it is a fresh build check this?? My Full Size RX with a December 2016 build looks like the one on left....

Did I get a reject slide or is Sig cranking these out like this now??

different coating batch mixed up by 2 different employees.

Are they both the same model? both compact 9mm?

Just asking because one slide might need to be heavier for the recoil if its 40 or 45.


My 9mm compact looks like your old one with the extra milling. Build date November 2016

Likely your right though that it was a running change to save time/money with how many they are going to need to crank out now with the military contract.. Hard to find a new one anywhere right now

Yup, both 9mm Compacts......I'm not sure why there are the extra holes in the old slides but they probably aren't for looks

Be interesting to see if anyone with Jan or Feb builds this year sees what i'm seeing

Running changes are not uncommon in manufacturing industries. They're typically incremental changes that may occur as production processes mature. You can always give Sig a call. I would guess (hope) changes would be documented but customer service may not always be aware of changes in manufacturing processes. It may be worth a call to find out though.

My mfg date on my P320c RX is Jan 17 2017.

It looks almost exactly like your new FDE slide.

My slide additionally has some numbers stamped where the front oval groove is missing. I don't see those numbers on yours.

Have you weighed them? If they're skipping steps, the pistol weight will be wrong. If they changed the design, it should still be right.

I'll weigh mine when I get a chance, but I have an optic on it, so it won't compare 1:1 with yours.

You're older slide on the left has lightening holes, SIG has stopped cutting them to make the slide heavier. Pistol slides (from any manufacturer) often have their weight chamged to compensate for other runnng changes in the pistol.
That "stainless steel part" is not a part, it is the hammer ramp and a machined part of the slide, it's just unfinished on the bottom. They obviously made the ramp deeper, again, a running change to address... something.
Do both pistols run well?

No, have not weighed but at least in my hand they feel identical. My slide does have the numbers you are talking about although they are very faint. Fwiw the other slide has these numbers as well.

Another thing I noticed different is the left side of the barrel block has a 3 digit number on it.

Thanks for checking, at least I know I didn't get a slide that skipped a station because Snuffy at Sig was taking a leak when it arrived at his bench.

In typical military fashion, crank em out. I think I may be going to the range tonight. We'll see if it blows up

You're not going to feel the weight difference in your hand, it's likely only a few grams.

There is no part called a "barrel block" regardless, many parts have numbers stamped on them to indicate the machine they were produced on, the vendor they came from or a revision.

Snuffy couldn't have missed that step because it's not done at assembly. It's done by a computerized CNC machine.

You're assuming that your gun was improperly built because SIG is cutting corners to keep up with a military build that isn't even final yet. Your gun is merely the newest revision of a gun that is receiving running changes as it goes thru it's life, as all guns do.
Relax and shoot, no one is trying to screw you.

Actually I wasn't assuming anything. Good natured sarcasm can be lost in translation



someone, somewhere is always trying to screw you whether it's today or 20 years from now

I haven't shot the new one yet, maybe tonight. The other one has had zero issues, I'm expecting the new one to run fine

As I said in the previous post sometimes stuff gets lost in translation.....just trying to point out my observations with a twisted sense of humor questioning Sigs motives heh

You haven't even shot the new one yet and your post title implies that there is a problem & that sig is cutting corners..
