Just updating my original post. My Benelli M4 finally came in a couple of weeks ago. I brought it home in pieces, unassembled in it's box. Curiosity got the best of me and I went ahead and assembled it to familiarize myself with the procedure. It's a breeze to both put together and take apart, and what is great, is that you don't even need tools. Anyway, I stripped it down again, gave it a thorough cleaning, and put on two coats of Frog Lube. The action in the Benelli is as slick as can be. When I finally had a chance to shoot it for the first time, I started off with about 25 rounds of high brass and followed immediately with the cheaper Federal loads from Walmart. It handled everything with no problem, even the cheap stuff. I can't say with any certainty that the Frog Lube is responsible for that, but it the action in the M4 seems to operate so smoothly and effortlessly that I plan on the continued use of Frog Lube. Like I said, it handled even the cheap stuff after almost no break in time. The S&W M&P 22 handgun, also operated perfectly on it's first outing after a thorough cleaning followed by two coats of Frog Lube. I noticed too that both guns cleaned up a lot easier than I've seen in the past. I'm sold on the stuff. So much so that I'm switching all of my guns to Frog Lube exclusively.
