I just bought a new LCR in 357 Magnum. My dealer had 4 samples and I noticed the older ones had a more polished looking grey finish on the cylinders. The newer one were a deeper black color, so apparently Ruger has changed the finish on the LCR cylinders. This must be one of the quiet evolutionary changes that Ruger does from time to time. I wouldn't have noticed except for the fact 2 older were sitting next to 2 newer LCRs.
