    Model 27 query re "front overhang on rear sight strap"

    Mes Amis, Tomorrow I pick up my latest addition to my S&W Military & Police revolver collection, a model 27-2 manufactured in 1970 I believe (from my S&W Standard Catalogue). The query I have is that the leading edge of the rear sight strap over the frame has a slight “overhang” over the checkering on the barrel. I have found only one image online that shows this may be correct. I cannot attach photos due to time restraints, and need to pay for the piece tomorrow (French time i.e. +5 hours or more from you folks).
    SVP advise.
    Merci
    RB

    I know you guys know the answer!

    Hi RB,

    I have one pre-model 27 from 1953 and two others from the 70's and all have the slight "overhang" of which you speak...normal.

    Mon Ami,
    I very much appreciate your reply. I can now go ahead (with confidence) in my purchase (as if I would have ever not for a S&W Model 27 acquisition, as they are not common en France) …… but now without having to explain to my better half why this particular S&W M&P revolver has such an “unique” feature. Which now begs the question ….. why is there an “overhang” over the rear sight strap onto the barrel checking area? I cannot think of an advantage to this design!
    Cordialement & Merci
    Robert

    RB,

    I can't explain the reasoning behind the overhang but will remind you to check the screws from time to time. I have had those sight screws shoot loose in the past requiring retightening.

    P. S....

    Never noticed before but it seems that all older S&W's with adjustable sights have that same "overhang".

    The advantage is in the cost savings for the factory as one sight fit multiple guns with no hand finishing expense and less inventory to keep.

    Bon Soir,

    I appreciate your point re cost savings in manufacture, however as the N frame was the largest frame at that time, what other frame was larger that required the extended rear sight top strap?

    I am still intrigued.

    The sights are different for different frame sizes, N, L, K, etc but I believe the cylinder window is different in regard to caliber i. e. Magnum VS standard cartridges and then the ACP cylinders were really short. I know some of this was accounted for with the barrel protrusion but I would think that if the he cylinder opening is a different size then the top strap length would have to be different.
