I've begun gathering parts to build a .44 tribute revolver from my late father's 50th Anniversary Blackhawk, and just found out Dave Lauck has discontinued his Flat Top revolver sight. Here's a link with photos of the sight:
D&L Ruger Flat Top Revolver Sight
If anyone has one of these that you'd part with, please PM me with a photo of your sight and a price.
Thanks.
