This is exciting news! I got the new 66-8 4.25" when it was released back in '14, and my first new purchase last year was the new 66-8 2.75". Which has me wondering if this new M19 Classic will have the cylinder lock-up of the 4.25" that it sure appears to be based on, or the newer lock-up design of the 2.75"? I like the 2.75" design better from an aesthetic point of view, but don't know that it's necessarily better. In fact, I've been wondering if newer 66-8 4.25" models have converted to the newer lockup design.

Anyone know for sure? I nosed around for some pics, but didn't see anything that gave me a good look with the cylinder open.
