X-FRAME, 10-SHOT .357 MAGNUM!!

SJshooter · Jan 27, 2014

I've posted this in the past, but another SHOT Show has come and gone without what would almost certainly be a big seller:

Take the Model 500 X-Frame and put a 10-shot .357 cylinder in it.

Imagine -- all that metal, the recoil would be minimal. 10-shots of .357 magnum! A reason for all us non-bear-country folks to buy an X-Frame.

DO IT SMITH!!!!

Alas, not possible. The eight shot .357 N-frame has a cartridge-rim exterior diameter of 1.6 inches that fits easily in a cylinder 1.7 inches in diameter. Increase that by 25% to accommodate the two additional rounds for a 10-shot ring, and you are at 2.0 inches. The entire X-frame cylinder diameter is 1.9 inches. There's not enough steel.

Since the diameter of the X-frame primer circle is only a couple of hundredths of an inch larger than that on the N-frame (the extra steel in the bigger cylinder mostly goes to the outside of the cartridges), I don't think you could fit even a ninth round into an X-frame cylinder.

I agree additional X-frame chamberings are possible, but I don't think it is possible to make any kind of X-357 that offers more than what you can already get in an N-frame.

You are probably correct, but an assumption is slightly off.

The "primer circle" need not stay the same. The N-frame 8 shot 627 357M has a larger "primer circle" than the N-frame 6 shot 629 44M. The OD of the cylinder is the same, but the barrel centerline has been moved further up the frame from the cylinder centerline.

X-FRAME, 10-SHOT .357 MAGNUM!!
