Very nice, S&W ucla! I like King sights, etc. While for collectors (aside from King collectors) they can detract from value, I always think that some guy cared enough about the gun to have the work done at the primo place for the time period. I've seen, on the internet, Sport models with weighted barrels, etc.
Read something, somewhere, where the added King underlug tube had three inserts: lead (steel?), mercury, and aluminum, with the idea being adjust/sequence balance to your liking.
Back in the day, shooters took bullseye seriously.
Any leads on how to read Skeeter's article you reference? E.g., publication/date, or anthology?
