there's lots of choices on how and what to clean with so trying a little of each you'll find what works for you. i usually clean with CLP, it's a cleaner/solvent and lubricant. if i start to see any copper fouling i soak my barrel overnite in hoppes #9 and then the stuff comes out pretty easy. there are good copper solvents out there that will probably work quicker. i use tw25 to grease the slide but i may try slide glide next summer during the hot months and see how that goes. i am a clean freak so i clean after each range trip so i dont let any significant buildup get started. i dont know if it helps any because of the coating on the slide but i wipe it down with a silicon cloth just before i put it away. thats probably just my old habit from growing up with blued barrels.
