Recently bought PDP Walther, now looking for night sights, not getting into a red dot.Changing these sights beyond my capabilities and my 68 year old eyes.If anyone can change them or knows someone who can please let me know, i'll gladly travel and pay more than fair price. PS gun purchased at advanced arms, they already told me they didnt have the right sight pusher, i think they are too busy or just not interested. Looking at the Ameriglos, any opinions ? PM or text,5704660533. Thanks
