New SIG question

[Outlaw75]

I just picked up a new M17 and I'm noticing a viscous looking white substance in the slide, almost Elmer's glue looking. Is this something along the lines of the anti-seize Glock puts in their slides or should I clean it out before I take it to the range?

Sounds like silicone grease. Do you have some pic to post?

 

[kidneyboy]

Have the same on my new 320 and 322. Looks like factory grease/lube. I did not clean any of it off and am probably 4-500 rounds into them combined w no issues.

 

[Outlaw75]

No mention of it in the owner's manual and I can't find anything on line.

My first thought was that it might be white phosphorus grease, but I can't imagine them putting it on so heavily.

ETA: Duh! I meant white LITHIUM grease.

It’s just factory applied goop, lots of guns have it. Clean it off and it’ll be fine.

Looks like TW25B, which is what was always recommended for use with SIG's in the past, and what I used on mine when I was using them.

I think you are 100% right.

 

[sparkyv]

Agreed. TW25B is a lithium grease. I like to run my SIGs wet, but that looks like an assembler's first day on the job. No harm done.

 

[JmacD]

Sig sells that as a “component”. It’s good stuff. That’s lots of it in one spot. I’d try running it because I’m a curious sort and wanna see what it would do. lol

 

[MEHavey]

Wow that's expensive stuff.

I think you'll like the M17.

 

[Outlaw75]

I think you'll like the M17.

I'm hoping so, based on the dry firing I've done.

 

[MEHavey]

You "may" have to take 10-thou off the front sight
to get POI to be POA+an inch or two.

If someone actually has a source for after-market Bomar-like
adjustable sights to fit the 320/M17/18 family, let me know...

That's what it looks like to me also. It is lithium grease and should be left in place when you shoot it.

It's to protect the rails, especially with a coated slide, when new. SIGs do like to run wet it you're going to practice much. You don't have to keep that much on it when you carry it, but make sure you use a grease and not an oil

SIG sells sights in various heights, and they all interchange. The original front sight of my P210 is now on a P365.

[MEHavey]

Yup ... got a set,

 

[NMexJim]

Note the extreme pressure and semi dry coating.

Me too.

Except Lubraplate is not "semi dry " and attracts grit

 

[MEHavey]

I've tried dry lubes that are in all other instances the absolute Cat's Meow.
(Luv`em)

For those loooooong sliding surfaces, however, grease (even though wiped
on very thin) is the only thing that truly seems to work well.

 

[bannockburn]

Nothing like it on my newer SIGs (M18 and P365), but had it on a P238 I got 10 or 11 years ago.

 

[sparkyv]

Not a problem for the way I run my handguns. I'm no "Operator" rolling around in the sand or mud. But, I'm interested in learning more about "semi dry" grease; would you please share?

I used to see that TW25B grease slathered on NIB SIG's many years ago, and back when I took my SIG armorer class (Classic) they said all their guns came with it applied. Maybe they're still doing it?

Anyway, I called the Mil-Comm folks to ask about getting some samples of their products for our agency range, and asked about it. They put someone on the phone who said he was a chemist, and one of the interesting things he said was that when you applied it to the guns, and rubbed it around the areas you wanted lubed, if you could still see the white color afterward, you'd applied too much. Always had good luck with it. They also sent us some samples of their oil.
