I carry my blued trs. Once a week...I pull another gun out of the safe to carry for the day while the trs gets sprayed down w oil. The next day I get it out and wipe the excess off and start the rotation again. I use remoil for this wipe down and have not had issues as of yet. Im in east Texas btw...very hot n humid.

 

First if you use a leather holster I'd go kydex w/ a sweat guard. When not on your person leave it out of the holster and wipe down daily w/ oil. If you pour sweat and grips are removeable, remove them and oil the frame. Some folks like Eezox and CorrosionX. A simple airing, light oily rag wipe down and non-absorbing holster does well.

 

It's pretty humid here in St. Louis, MO. I carry a LB Stinger IWB, most days. Every night, I wipe the ol' girl down with a lightly oiled gun rag. It's a blue pistol with some carry wear, but no signs of rust - ever.

If your really concerned with the finish, hard chrome is an excellent choice. Perhaps on your next acquisition...

 

At the end of each day, a light coating of oil will probably eliminate the problem.

Stainless would also help, but that requires a purchase.

 

I have been using Ren wax on my safe queens for years, great for long tern storage. For EDC I have not come across anything better than Eezox, it has never let me down.

 

Carried for three years in Miami.....I removed the pistol from the holster every night, and wiped with a silicone cloth every night. Field stripped and cleaned every Saturday. Carried a few blued 1911s, never had an issue.

Everyone is a bit different. One guy I used to shoot with could corrode a Glock.

 

Sweat guard holster, wear an undershirt between you and your gun and wipe it down regularly.

 

I did everything everyone suggested and my slide still rusted. I painted the slide using Dara Coat and it helped. I hate to say it but the only pistols that never rusted is my Glock 22 and Glock 27. Good luck.

 

Might have something to do with carbon content of slide.

 

Try lithium wheel bearing grease, no kidding.

I have a tube of Lucas Red "N" Tacky #2 front of me right now that I have had for years that I have been using on my M4 (both here in El Paso and in Afghanistan) and on an AK and SKS. I have also used it on my 1911s during the hottest times of the summer to protect it from the ill effects of sweat. It works great as a lube for the bolt and slide and has an added benefit of corrosion protection.

On the tube: "Red "N" Tacky is a technical blend of lithium and polymers plus a heavy addition of "anti-seize" agents that set it apart from similar greases. User can expect the following:
- Good Temperature Stability
- Good Resistance to Acid and Alkali (Read Sweat)
- Good Resistance to Rust and Corrosion"

As a lube for the bolt / slide, just use a very small brush and dab a tiny amount on the bristles and then brush onto the rails.

For corrosion protection, I use a cheap $3-4 dollar shaving brush and dab it into the grease (again, just a tiny amount) and brush it on the exterior metal surfaces. I do this outside and then let the 1911 or rifle set in the sun for 5-10 minutes on one side and then flip it on the other side for 5-10 minutes. The sun heats up the metal allowing the grease to 'get into the pores', then I wipe it down with a clean rag.

Don't put too much on as when you fire it you'll really have a 'smoke wagon'.

 

Try Kroil to remove the rust... just picked this stuff up, stinks, but works great on removing crud and a little light rust I had on some old spare parts I forgot about.

 

Robar NP3 (or NP3+) and no more rust problem
