I have a Colt Mustang Pocketlite as a back up, and poor eyesight. I needed a dot front and rear system. The Colt had the normal blade front sight, no dovetail whatsoever. I took it to Davids gunroom on Buford Hwy in Norcross to see what they could do, I talked to the smith and he offered several options. All involved grinding off the front blade and cutting a dovetail to accept the new front sight. I was really, really worried about how it was going to turn out. Anyway I left my prized Colt with him and picked it up three weeks later. AWESOME JOB, I was amazed. Now I can actually see my sights and the finish is perfect. I can't remember his name but he is still there, I see him all the time when Im picking up reloading stuff.
If you can't find someone local it would be well worth the drive!
