Be careful with gun cleaners on those Ahrens grips.
That is the brand that S&W uses on the 327 8-shot PC snubbie I have. The very first time I cleaned it, the gun cleaner I use dissolved the finish on the grips!
That cleaner, MPro 7, is sooooo gentle that I have used it for over a decade on EVERY gun I have owned, and it has never attacked ANYTHING. In fact, the maker of it says you can wash your hands in it, and I often DO! Yet, it dissolved the finish on these grips.
So, be careful.
