I have little to add but pictures...
But I will say, I never considered a "Dirty Harry gun" to be anything other than a blued 6.5" Model 29...not a 4", not an 8 3/8", not nickel, certainly not a 629...and don't even get me started on the .41's and .45's.
In the name of authenticity, I believe it was Dade speedloaders that Eastwood carried in his pockets.

I've had this one since '75.
Long ago I replaced the red ramp front sight with a plain ramp. I have nice Herrett's stocks on it nowdays after years of swapping.
While it never belonged to Clint, Harry or John. I like this 29's pedigree much better - it's mine!
Sometimes though, when I am looking away - I could swear it was a Model 57...
Once and for all, for gosh sakes - THEY WERE MODEL 29's - NOT 25's, NOT bored out 44's to accept 45 blanks, or any of these other asinine stories that keep creeping in.
That book I spoke of in post #32 really needs to be written. That these silly rumors continue to be regurgitated as fact becomes more and more ridiculous.
For the newbies here, use the search function on this - it's been hashed out time after time. The facts are known and they're available.
I have always heard it was a 29-2 with a 6 1/2" barrel. Millius stated in an interview that they wanted a 4", but they weren't that popular at the time and S&W didn't have any short barreled guns in stock. They did have the longer barrel so they went with it instead. After the movie they became immediately popular and the prices soared.
