As suggested yesterday, here’s the granddaughter’s cousin, once removed, of the old Colt .41.
I had one guess in the comments, & it was oh so close.
This beauty is a S&W Model 58, the "police" issue version of the civilian .41 magnum, the Model 57. 4" barrel & fixed sights, nice deep blue finish, & I like it.
I couldn’t find a source to check the age by serial number (anyone?), but the minimal research I did do indicates this model was introduced on July 10, 1964, & was discontinued somewhere around 1978/9.
That would make this young lady around 36 years old, if you split the difference.
A little young for me, but I’ll make a concession.
Y’know, it’s fun handling these neat guns, but alas, I can’t shoot them.
(Hmmm...mebbe if I talk to the Colonel…)
