They look great.
I just received my first set from them for a Walther P38. Wood was nice Black Walnut, real wood no "laminate", the exterior shaping, fit and finish were perfect. Drop dead gorgeous! The insides of a P-38 grip is a maze of ups, downs and cut outs....the fit was spot-on. They even sent 4 different length screws to get a perfect fit. P-38's were war time manufacture by several different makers so frames vary big time!
I'll give Altamont a big 10+ for fit, finish and the extra screws are a big +!
