In the course of gathering spare parts for a 457 pistol I recently ordered a Rear Sight (Low Carry; .360") SMITH & WESSON | 10, 40, 45 SERIES SKU: 339450 from Numrich figuring it would either fit or I could get it machined to fit. After receiving the sight I saw it is a skosh higher than the factory plastic sight but the base looks like it will slide in as the edge fits the 457 slide dovetail. The height compensates for my testing (flinch?((which is very consistent))).

Any thoughts from the community on if this will fit the 457 rear sight dovetail? Also, is there a metal front sight available?

By the way, as has been reported here, the 457 is very pleasant to shoot. Very nice handling characteristics. Mine had a very good trigger after cleaning and lubing.
