From a Canadian perspective
The .327 is off the table as all .32 cal handguns are prohibited.
Ruger had talked about releasing a 4.2” LCR for the Canadian and Californian market.
When our handgun transfer freeze is inevitably thawed out with the 2025 election I would love to see the 4.2” .38 LCR resurrected. Preferably in the DAO shrouded hammer guise.
I have a 4.2” SP101 and it’s amazing. Really smooth gun with tight cylinder gap that handles full bore magnums like a champ. The single action capability is entirely unnecessary and the gun is quite heavy.
I’m very LCR curious as a more modern streamlined combat revolver.
