8mm/06. Congrats on your 50th BD.I hit the half century mark a few months ago myself.
You said your better 1/2 said you could get a 50th anniversary SS.The 50th only comes in blued with the 4 5/8 or 4 3/4" bbl,whichever it is.Not that that 1/8" makes a difference one way or the other.I picked one up a few months ago.They only come with the fixed sites. I was hoping they were offered in a longer barrel but unfortunately they don' t.If I were buying one to use instead of putting away I would get the longer barrel,adj sites and in S/S.
