S&W 10, 64, and 87 - what versions +p rated?

[kerank]

Does anyone know what versions (when) the model 10, 64, and/or 67 were rated for +P ammo?

I'm looking for a good .38 (probably used) and want to make sure it will be rated for +P ammo.

Thanks.

I would think the all of the 64 and 67 series would be good for +P. As for the 10, anything made in the last 40 years should be OK.

After all, how much difference is there between a 10 and 13 other then cylinder?

Just to add to mikec's response if it has the heavy barrel it is +P rated. If you want one for concealment try to find the 3" version. It offers a shorter barrel but has the full length ejector rod. Don't forget the .357 K frames either.

All model numbered steel K frames are +P rated; a heavy or light barrel makes no difference.

Heat treatment of the frame, slight reenforcement in the crane/yoke area as well if I remember correctly. There were in fact several hundred .357 Mag chambered model 10s made for either NYSP or NYPD a few years before the model 13 was introduced.

The principal difference isn't in the frame, but the cylinder. Magnum cylinders were made from a different alloy steel, and heat treated differently.

You have to shoot a lot of Plus P ammunition to see any effect, but what eventually happens is cylinder back & forth play (as opposed to rotational play) that is caused by the cylinder battering the end of the soft yoke barrel, on which the cylinder revolves. This is not hard to correct, but S&W saw no reason they should have to fix it under warrantee. They say, "absolutely no" on pre-1957 revolvers, partly because they don't always have parts to fix them.

Not to be redundant, but would the newer 10-8's be considered to be any stronger or "improved" for +P ammo longevity?

 

[SaxonPig]

Since +P really isn't higher pressure at all, being loaded well under industry maximum pressure for the caliber, ANY quality made revolver in .38 Special will "handle" +P just fine.

No special "rating" is required.

As a test, I shot about 1,000 +Ps and another 500 rounds of my handloads that are significantly warmer than +Ps through a 1942 M&P ("Pre-10") with no signs of wear or damage to the gun. Factory +P ammo in ANY post-war S&W would cause me zero concern.
