Royal Purple Gun Lube
Most people who are into cars have heard of Royal Purple. I have used Royal Purple automotive oil before, and I can attest to the difference it makes in the way your vehicle performs. Knowing this, when the opportunity arrived to check out Royal Purple Synthetic Gun Oil, I was more than willing to give it a run. My test pieces were a Ruger P89 in 9 mm, purchased in 1994, and a SIG Sauer P229 chambered in .40 S&W, purchased in 1998 while I was stationed in Germany (yes, a real German SIG, not SIGArms). Both of these pistols have had hundreds of rounds fired through them, and I cannot remember a single FTF or FTE with either. The ammunition was Monarch .40 S&W, and American 9 mm, which was head-stamped PPU.
To start off, it isn’t purple; it is a clear yellowish color, similar to Remington’s Rem Oil, and smells about the same. Spraying and rubbing a small amount between my finger and thumb, it didn’t feel any different than many other firearm lubricants. Being in a pressurized container, even a small squirt can dispense more than what you want. One thing I do not like about it is the spray can. Without the small tube, the pattern is very wide, and overspray is easy. With the small tube attached, the spray pattern is not only wide but shoots much farther, compounding the overspray problem. I feel it would be much better packaged in a small tube or spray bottle as opposed to a spray can. I disassembled both pistols and stripped the previously applied lube with FrogLube solvent. To ensure all lubricant had been removed I partially assembled each, feeling for metal-on-metal contact. Once I was sure all had been removed, I gave a light squirt on the barrel, chamber area, and a couple of small squirts on each frame at the front and rear of the slide rails. That’s all; none was applied for the rest of this test session. At the range I fired over 500 rounds, 300+ through the P89 and 250 through the SIG, without a single malfunction, which is exactly what I expected.
This is just an initial test, as I will be running the oil more with my pistols and a couple of rifles. I also have given a can to one of the RSOs at my local range to run on his AK, which I should hear about soon. Would I use this product again? I would. While I am very particular about the types of lubricants I use in certain firearms, Royal Purple Synthetic Gun Oil has risen almost to the top of my list for preferred firearm lubricants, which is a very short list.
Pros
Works well, no malfunction over 500+ rounds fired. Once applied felt very slick on guns, some pieces felt to be “floating” across each other. Will continue using on the tested and other firearms.
Cons
Too easy to overspray or dispense too much.
