I sent a Kimber to Clarks for fitting a 460 Rowland kit about 2-3 years ago, and when it came back my night sights were messed up. So I sent it back to Clark and they installed new ones for me. Now the front sight is dead and the rear ones are faint. Maybe the only reason I should care who made them is not to repeat the same mistake again, but I would like to contact the factory and see what they would do. The front sight has the P-TH3 stamped on it and the rear has P-T H3. Any ideas whose these are?
