Thats funny that you posted that wood. Its the exact color that i have ordered for my .375 JDJ (silver frame). Going to get it from Tony's Custom Grips/Forends. My .375 doesn't kick too bad with the break installed on it. But I'm not going to lie, about 20-25 rounds into it my right hand goes NUMB. Can't feel anything for half a day. Yeah Jim is done, but Tony does a really good job.
