    Hi all,

    I have recently acquired a Stainless S&W Model 66-4 with a 4” barrel.

    [​IMG]

    Anybody know how to find its birth date?

    The serial number is CAE 1XXX.

    Is it safe to shoot 125 grain .357’s through it?

    As I researched the gun, I ran across several warnings about shooting 125 grain .357’s through Model 19’s.

    I don’t know if it applies to model 66-4 or not.

    Thank you in advance for your help.

    MODEL 66 COMBAT MAGNUM
    - .357 Mag. cal., K-frame, satin stainless version of Model 19, has 2 1/2, 3 (disc., only 2,500 mfg.), 4, or 6 (disc.) in. barrel, current production uses Uncle Mike´s Combat grips, 32-39 oz. Disc. 2004.
    Grading 100% 98% 95% 90% 80% 70% 60% 50% 40% 30% 20% 10%
    $390 $320 $230
    Last MSR was $614.
    Add $11 for 2.5 in. barrel.
    Add $29 for 6 in. barrel (disc.).
    Add $48 for TH and TT with 4 (disc. 1991) or 6 in. barrel only (disc. 1999).
    Note: Several models of the Model 66 were made - such features as an all-stainless steel rear sight and a recessed cylinder will bring a slight premium if NIB. There have been 6 engineering changes to this model. I believe that the -4 denotes engineering change.


    This is all I can muster. Have a gun smith look it to determine shoot-ability.

    The K frame Smith can shoot .357's no problem, but not as a steady diet. A practical approach is to practice with mostly .38's and only a handful of .357's for familiarization. Then load .357's for self defense.

    The 19 and the 66 should not be fed a steady diet of the light (125gr) .357 rounds as the forcing cone could be damaged and the top strap could experience flame cutting. I've never heard of a problem shooting heavier weight .357 loads in them...

    The 66 is a perfectly capable revolver. It does have some limitations though. A steady diet of any Magnum ammo is not advised. "Some" Magnums will not seriously degrade the gun. Exactly how much is "some" is open to debate. Personally, I would consider 50-100 Magnums/year an acceptable amount. With this kind of diet the revolver will last a lifetime.

    What a sweet gun. You'll love it. I had one but gave it to my brother for doing me several huge favors. I was in Michigan over Christmas and we went to the range with all of our guns and I got to handle and shoot the baby again. Ahh sweet joy!

    I just bought a 66-3 and according to the book at the dealer it was made late 1989 to early 1990. I hope that helps some. It is an awesome handgun. The older I get the more I appreciate the older S&Ws.

    My 66-1 is my favorite .357. The accuracy outta a 2.5" barrel at 10 yards amazes me. I shoot mostly .38 specials outta it and it just rolls in DA so smooth with perfect timing. It's just a joy to shoot. With .357 loads you'll notice a bit more recoil, but nothing unmanageable. Have fun with it!

    This is a twin to my 66 and I feel the same way about it.

    I can't imagine a .357 Magnum that can't take a steady diet of .357 Magnum rounds. My Colt King Cobra has been fed "hot" .357 Magnums since 1968 and it's never had a problem of any sort.

    Colts and Rugers were built a lot stronger than the model 19/66. A S&W N frame .357 (model 27 or 28) did not have the same inherent weakness. I shoot anything in my Colt Troopers as well. The only rounds that could cause trouble in the Smith's were the hot 125 grain .357 loads. The S&W forum has detailed info on this as well as pictures of damaged forcing cones and flame cut top straps...

    I bet they could "take" it but I'll admit it. . . I baby my Smiths, but they are all older and in near mint condition and I wanna keep them that way (I know, excuses huh :eek:). Don't get me wrong I still shoot 'em with all types of loads, just in moderation. I got plenty of Rugers for truck, mountain around the state guns they get abused and they like it. ;)
