SURPRISING gun lube experience!

[kudzu]

Hoping this might help others, I am shamelessly posting it in multiple places.

Immediately after buying a Sig Mosquito .22 pistol for my kids to use, I field stripped it and thoroughly cleaned and lubricated it according to the owner's manual, including placing a drop of gun oil in a hole just behind the ejection port. I used HOPPE's Elite Gun Oil.

On the first trip to the range, the pistol would not go, "Bang," and there was no firing pin dent on the cartridge rims. When I called Sig customer service, after asking questions about dry firing, lubrication, ammo, etc., he asked me if I had any Rem Oil. I told him that I did and he told me to put a drop in the hole behind the ejection port and try the pistol a few more times before sending it in for them to take a look at.

One drop of Rem Oil and the pistol fires and cycles without a hiccup! I have no idea why that particular oil made the difference. I do see that on the Rem Oil bottle it says "Contains TEFLON Lubricant." Maybe that is the difference?

The next time I clean the little Sig, I am going to use Rem Oil for the entire lubrication process. If you have a semi-auto that is not behaving, it's worth a try before taking more drastic action.

HOPPE's Elite Gun Oil is a high viscosity oil. When you have close tolerance parts a thick oil can cause problems by creating compression. By using Rim oil it essentially changed the viscosity and thinned it out causing the excess thick oil to escape.

What he said ! Your little Sig will probably be more tolerant of Hoppes as it gets broken in.

I use Rem Oil on firing mechanisms and tight fitting parts with good results. Also use CLP or grease on higher stress/bigger tolerance parts for longevity.
