    Colt Diamondback Rates for plus P ammo?

    Anyone know or how to confirm if a colt diamondback snubnose from 1976 is rated to shoot Plus P ammo or only 38 special?

    I just donít know if it canít handle plus P ammo. Thanks in advance.

    My gut says No.

    A steady diet of +P? I've shot quite a bit of spl and some +P for zeros and function in my 2 1/2.
    1977 vintage.
    Carry the +P.
    No issues.

    Virtually all steel-cylinder revolvers will handle +P. The proof loads fired at the factory exceed +P pressures. Now, the wear on the gun from a diet of those pressures is another thing. I do not think that an electron micro comparitor could detect the difference between a DB shot with low pressure loads and one sighted in with +Ps.

    Colt's legal team will say no, of course.

    I may be somewhat of an anachronism.
    If I want more whack, I use a bigger gun.
    I'm not all excited about hot loading, either.
    My stuff shoots better and handles better with rounds that aren't a lot of commotion.
    For practical purposes, you won't wreck a revolver with a few +Ps.

    Thanks all for the input. I probably wonít hammer it with plus P ammo but just wants to confirm it wonít break the gun if I had to use it.

    I think Colt considers all post-'72 steel D-frame revolvers ok for +P ammunition but cautions they should be checked every 3000 rounds for frame stretching. For aluminum frame revolvers they recommend the frame check every 1000 rounds. How much of a danger there is...who knows. Gun scribe Massad Ayoob claimed Colt chambered a D-frame in .357 as an experiment and ran it several thousand rounds without problems but decided not to sell such revolvers as they felt there was no market for them.
