I can't offer any argument, they are incredibly cool. I really like my 4" M27-2. Never realized how scarce those are until I joined this Forum.
One thing I have always wondered about. Why is this the only model they put the fancy checkering on? I would think the .44 Magnum, later called the M29 would be a good candidate for it. If I had to guess, I would say it was because when the .357 Magnum came out in 1935 it was the top of the line gun. In 1956 when the .44 Magnum was offered it's only outstanding quality was caliber.
I'd like to hear others thoughts on why the .357 Magnum M27 and it's Pre variants were the only ones that got this treatment.
