This has been discussed before, I think you will get mixed answers, some say no problem, some say ANYTHING you do to an original pistols affects it's originality. When you remove the grime, you also remove its original finish and replacing it perhaps with the same type of finish. If they are really oil soaked around the edges and the outside you may actually make them look worse. If it is just surface grime like those in my FAQ cleaning tips you are okay! A bit of a gamble. If it is just grime on the outside of the wood you are stripping the covering, if it is oil INSIDE the wood, you wont be able to get it out and you will have that oil show up EVEN more as dark streaks. There are some products that bleach the wook or strip oil from the inside and I would NOT recommend using that on original grips unless it is on a shooter Luger, just MO. ~Thor~
