i just came up here from the Black Powder and cowboy gallery and saw this thread. Small world. Just yesterday I stripped the walnut grips of my BP 1851 rebel navy .44. Yes I used CITRA-STRIP for the first time. Got it at Home Depot and used the spray can. It worked GREAT!! used one of my plastic gun brushes and blue towels and it took two applications to get all the little stubborn spots.
But the best part is the wood is spotless and ready to refinish. I did not attempt to take any of the color off, just the lacquer. I want to oil the wood.
good luck and have fun.
