My first gun was a Model 66 6". I loved that gun, but as a young fellow I thought I HAD to have that new super-strong L-frame 686. Boy, I wish I had that old 66, and I wish they made them new again...without a lock or two piece barrel.
My first handgun was also a 6 inch 66-2. I agonized over the same two choices, but I bought the 66-2, and still have it. Funny, I never warmed to the L frame.
Sorry about the ugly Pachmayrs, but this is my dishwasher safe gun.
