Well, I just gave my new S&W's their first good cleaning. I've shot about 250 rounds through each one and I figured I needed to clean them. I forgot that these things had so many "barrels" to clean. 7 on one and 8 on the other. I could have cleaned 4 of my XD(M)'s in the time that it took me to clean 2 of the revolvers. Oh well! At least they're clean for right now. Gonna dirty'em up pretty quick and they will probably stay dirty for about 1 or 2 thousand rounds.
