I'd have to go with the good old 64
I've got 3 of them, a 64-3, 64-7, and a 64-8.
I have an NY-1 64-5 on the way.
From the "pinned" era, this is my favorite. It beats my Model 10's only due to ease of maintenance and stainless is just more carry friendly.
.38 Special is my favorite round of all time, and the 64 was (and is) a stand by, go to meat and potatoes service revolver that has done it's time in countless duty holsters on some of the toughest streets in America. It can still be found in use by many Corrections Depts. and security companies.
I'm a PA State Corrections Officer and I've qualified with both 64's and 65's. The 65's at my job are not the most well cared for, stainless is a must for these kinds of jobs, where the gun gets handled and carried by several people every day, is in service 24/7 and treated with about as much care as a flashlight.
No nonsense, drop 6 rounds of +P in the cylinder and put it in your holster. Goes bang when needed, no unnecessary target sights to mung up. Shoot 6, reload, repeat......it just does the job. I have fired my fixed sight revolvers out to 100 yards and hit the target.
