I thought they were all identical except for length. But figured I would make sure I wasnt overlooking something.

I cannot provide a link. This is a conversation in a f...book group. I was giving my opinion as to why a wheel gun is better than a 1911 in 10mm. My argument was the extra calibers, and the fact 10mm is really suited for hunting unless your Ted Nugent Especially the 10mm Mag. My other point was the pre lock 610 will/should increase in value while the 1911 will only decrease. Now to just get my hands on one for a reasonable price

Maybe this isnt the place to ask, but what models of the 610 are pre lock? 610 and 610-2? If so what changed to make the 610-2? And why is the price so much higher for the 610 than a -2 model or maybe the first answer will cover this as well?
