What are my sight options for my 640? It currently has the ramped, serrated black FS. I like the one with the orange insert on the 342, etc. Where can I find one?
The other option would be the XS Big Dot. WOuld I have to mod my 640 in any way to accept this sight? I remember glunblast installing one on a 342 and they drilled out the pin hole.
