Oh the rust, month old 15 rd mag rust inside the mag body and 2 12 rd mag exteriors had light rust even though wiped more often than not. Removed the rust and shot it with Norrells moly resin about 2 months ago to resolve those issues. Last week noticed some rust on the top of the front sight that I will address shortly. Nothing yet to report on the slide itself, but is only a matter of time till my acidic body chemistry claims another victim. I should just go ahead refinish the slide and put any worry to bed but I'm not at that point yet.

I've hiked and sweated on mine (tip; the 365 will run snakeshot, and keep two rounds at the top of the magazine), thus far, no problems. Had a little surface rust on a magazine; a quick wipe took care of it.

I have rust starting on my new xmacro, same place.

Boeshield T9 and Renaissance Wax will prevent sweat corrosion on IWB carry pistols.

I get considerable rust on my P365. I need to check it often. When I go for a bike ride, it's on a bicycle, not a motorcycle, so my gun gets a lot of sweat.

I've been using Gunzilla, changing up to Eesox (I might give Boeshield a try). I don't know if that will be better or not.

I'm seeing rust in several spots. Around the rear sight, the magazine tube, both inside and out, on the outside of the slide, and near the front of the slide. Also, it has a WC grip module, and the magazine release tends to rust considerably. The mag release and magazine tube are where I see the most rust.

Is this something I'm concerned about? Not really. Certainly, I don't see it as a manufacturing problem. I must stay on top of it and protect the gun with a rust inhibitor.

Hose it down with Boeshield T9, wipe of the excess and let it dry. Then apply a couple coats of Renaissance Wax, letting it dry between coats and buffing off the excess. Water and sweat will just bead up and roll off when you are done.

How long does the wax hold up against the oil used when cleaning?

I reapply every time as part of the cleaning routine.

Two of my 4 P365's have had some issues with rusting from moderate carry. Annoying, but not enough for me to make a hubbub about it since I carry/use my guns a lot. I just make sure to oil them a little more.

 

[Phoenix.]

Haven’t had any rust issues.

Mine does get cleaned and lubed once a week after going to range, so that may help.

 

[Mike-AK]

Here in AK I have been using Johnson’s Paste Wax for decades for metal and wood protection. A few years ago I switched to Renaissance Wax. It is a better product for firearm use IMO. A small can will last you a lifetime. As far as the rear sight rusting, spray some Boeshield T9 on it and wipe off the excess. Do that every time you clean and the rust problem will go away.

Welcome to Sig Talk.

Not sure what could have caused that. I’ve never had rust on my 365 that’s also over a year old.
I did experience rust on a 12 round 365 mag that was brand new a few months ago.

First time I experienced rust on any of my mags. I believe in my case it was from carrying the mag in my pocket this summer and it got some moisture from sweating or maybe contaminated from something in my pocket. I usually carry a extra mag in a IWB mag carrier but it was printing a lot when wearing slimer fitting
t shirts this summer.

I too have a few 12 rounders that have small spots of rust. I’ve never had any Sig mags rust, a little concerning.

Not flexing here but I have 5/365 variants. Some are 4+ years old and none have rust.

A gunsmith of 40 years told me about this and, well, his experience has paid off.

After cleaning them post range trip, I thought they were clean using several different products... nope!
It cleans and is a dry protective lube for both the inside and outside of firearms.

No idea why this isn't well known?
Well, at least to me... until awhile ago.

I have not had rust problems, I carry it every day but I also tell you that from time to time even when its clean, I give it a coat of Remington oil, which is very dry and does not stain.

Tricholoroethane (aka Eezox) is/was an industrial solvent in wide use, until it was identified as an ozone-depleting substance. It's not something that folks would see in the same scale as in years past. It'd be my guess that that's why it's not as popular in general use, as it used to be.

Same for Carbon Tetrachloride, which used to be put in fire extinguishers. You don't see that any more. Good solvent though.

On topic: I have TCE (Eezox) and use it sparingly on new mag bodies (in and out) when new. It hadn't occured to me to use it on sights or the mag release, but that is a good idea. I'm don't have sweat that corrodes things, as far as I know. Still, good prevention.

Rennwax is good stuff, I use it on a blued 1911, mostly. Paste wax would probably work as well.

 

[Mike-AK]

Eezox is chlorinated, which is bad for guns and really bad for people. As the solvent breaks down, it releases chlorine which can cause stress corrosion on metal parts. Ruger learned that the hard way when they used a chlorinated lubricant to lube the threads on Redhawk barrels during assembly. That and Eezox just smells plain disgusting…like cinnamon and cherry cough syrup.

Similarly, I wipe down my EDC with a silicone cloth when I take it off at end of every day.

When I clean it, I put a drop of oil in/on mag release with a needle oiler.

Is Rennwax just a shortened name for Renaissance wax? I've read it's a quality product and it's been suggested as well.
