A friend of mine was telling me that I needed to lube the gun so it would operate more smoothly and be less prone to failure/jamming etc. He was recommending something called Metrotex or something close to that, I'm not sure what.
My father taught me to clean the my guns meticulously with good cleaner, but we never lubricated anything...of course this was always hunting rifles, and it may be different for semi-auto pistols. If someone could enlighten me on whether Glocks need this, and if so, what's a good product to look for, I'd appreciate it.
Also, what are the benefits/drawbacks/considerations to using lube?
