I think the LCR or my preference the exposed hammer LCRx is an excellent design with a great trigger and the only really effective two finger grip (no pinky support) I've ever used. But I would not touch one in that oddball caliber unless I planned to stock ammo deep or I had slept through the prolonged ammo pricing and availability issues in 2013+ and 2020+. Even then cost and lack of load options, and every small reduction in bullet diameter limiting what can be done in effective bullet design, I personally would not get into .327. Trying to talk you out of it as requested!
I will also report crimp jump is not a maybe issue with 9mm LCR, it's a major issue so you essentially have to test 9mm ammo down to the specific lot when you by a new case. First hand experience, even with maximum grip force applied to counter the light weight of the revolver I've had the 5th bullet and powder laying loose in the cylinder. This negates some of the advantage of the wide range of loads available in 9mm, and the ease of picking up 9mm off the shelf anywhere in a pinch.
If you really want light weight I'd go with the .38+P LCR/LCRx. I'm willing to accept a few more ounces for the short barrel .357 version (roughly the same weight as the 9mm models) for maximum durability, ammo supply flexibility, and then carry with a good .38 +P load for recoil management and shot-to-shot speed in such a light revolver.
As to hiking, I think it would be simpler to get a good belt holster for the P365. I've hiked a lot of miles, mostly with G19 belt holster. I'd never consider hiking with IWB or appendix carry for comfort as well as potential injury, even just wearing holes in your skin. If I'm going deep concealment enough to carry a P365 I use an IWB holster, but specifically bought a strong side OWB holster for anytime I'm carrying the P365 and get into any hiking or other physical activity, including the potential need to walk if a vehicle breaks down (throw the OWB holster into the trunk pack).
So I'd just find a better holster for the P365 and you are well beyond worrying about 5 or 6 round capacity, .327 or 9mm ammo issues, or adding training time for a different handgun. (My intent for the LCRx is a backup gun to a 12-15 round 9mm on rare occasions.)
