I think there would be a concern for the 327's high pressure level in a gun that small. It is not a grown up 22 like the 32 S&W. The cartridge is more like a compact 357 Magnum but even higher pressure.
That's why I said it'll never happen.
Even though it could probably be done with modern materials, the 45,000 psi MAP for .327 Federal would likely be too close to the design limit of the cylinder (not enough safety buffer).
But, people said the same thing about the LCR...
"Can't handle the pressure."
"Too much for the frame."
"Ruger says it can't be done."
Etc.
Yet, here we are with multiple .327 offerings back on the market from Ruger, including a .327 Federal LCR.
I still don't think an I-frame sized .327 will happen. But I'll buy one if it does...
I think there are platforms where .32 H&R Magnum is just about perfect. This might be one of them. I also would have loved to see a dedicated .32 H&R Magnum LCR on the lighter frame they normally use for .38 special. The new .327 LCR required the heavier frame that they use for .357 and 9mm.
I agree that it would be a great product for the guys that just want .32 H&R.
But, the weight isn't a big deal.
The .327 LCR weighs 17 oz.
The .38 Special LCR (1-7/8") weights 13.5 oz.
I went from a 14.8 oz J-frame to the .327 LCR, and the difference (2.2 oz) is inconsequential. I don't feel it, at all. If anything, the LCR is actually more comfortable to carry, which gives it the edge. Why I find the LCR more comfortable, I don't know; since, the 642 was more compact (on paper), and I'm using the same holsters.
