Pressure and power are not necessarily related. The 357 cylinder has to stand up to up to 35,000 PSI of average pressure (plus any safety margin). A 9mm +P cylinder would have to stand up to 38,500 PSI. I believe the 9mm case head is slightly larger than a .357 as well, meaning the cylinder would be ever so much thinner.The 9mm LCR is on the same frame as the 357, and 357 is serious power in a small revolver. I doubt anything in the 9mm LCR is light duty, compared to the LCR 357
what I've heard you won't want to shoot the hot 9mm stuff from the lcr9 anyway.or is it??
The 'main' manual which does NOT include the 9mm specifically mentions the LCR .38 is rated for .38+p, the addendum for the LCR 9mm makes no mention of a +p rating, nor is an advisory against the use of +p given.
Is the 'honeymoon' over already???
My question is if the LCR in 38 spl +P is available why get a 9 mm?
