The PC comes with the rubber Hogue grips as well as a pair of Kim Ahrends unidentifiable wood. The PC has forged hammer and trigger vs. MIM. It comes with a gold bead front sight vs. the red ramp. It has a ball detent lock up. The $200.00 extra gets you plenty of goodies. Now, all that being said, the Pro is a very nice gun. My wife loves her PC. I like shooting it once in a while, but the gun is just too easy to shoot. When you get used to the moonclips, they are quite easy to manipulate. At first, you will cuss at them and want to go to standard speedloaders, but even full-length Magnums will be twice as fast as an HKS after a little practice with them. the .357 moonclips demand a demooning tool, so plan to buy or build one. Is it worth it? No gun collection is complete without. Now, it can be said that no gun collection is complete. Period. --but, you should get a 627. Get a Pro, get a PC, it comes down to preferance at that point. You will love it. They are wonderful.
