I would have blown the extra hunny for the Pro, but I have the standard frame (Pro wasn't out yet) and it is all that you will need. The swing out hammer would be nice, but I really don't have any problem with the standard hammer either. I have a ML barrel w/ a 1x scope, a 204 w/ a 4-16x50 Bushnell 4200 Elite and a 7mm-08 pistol w/ a 3-7x32 Bushnell 3200 Elite. Hammer isn't an issue with any of them. All of the barrels are shooters and you will have a great time with this gun. But you will spend a lot of money also!!
I'm looking to get another frame so I don't have to do so much changing. I would recommend getting an oversized hinge pin right away, that did wonders for my 204 and ML groupings. Also a 25 ACP conversion for your ML barrel when you get it.
