Please forgive my ignorance, but I just purchased my first Glock, and have a question. I have always had revolvers, and when I got my CWP, I used a S&W 442 as my primary carry, mainly because if there is a chance in ten million of a pistol malfunctioning, it will be mine, in a circumstance when I desperately need it, (you just have to know my luck. LOL!) so I thought my odds would be better with a revolver. Anyway, I always said that the only pistol I would trust my life with would be a Glock, for their dependability, but couldn't afford one. I finally saved up and bought my G 19 and love it! I've run about 500 rounds through it with absolutely no problems whatsoever. But while recently looking through accessories for it, I came across an ad for Lone Wolf Stainless Steel Guide Rod Assemblies for Glocks, and they state :" The factory plastic guide rod can crack, chip or break, causing feeding or ejection failures". Obviously this is not what I want to hear, but in researching for so long before buying one, I never ran across this as a problem before. Is this just an advertising hook for them or is there potentially a problem with this? Just wondering if this should be something I upgrade or not. Like I said, please forgive my ignorance as I am still learning. Thanks in advance for any advice!
