I have a 610-2 and a new 610-3 both in the 6.5" tube. The -2 model was the classic with a solid cylinder. The -3 has the fluted cylinder. I bought the -3 model for the day when I wear out my -2 model which is my primary revolver when shooting USPSA in revolver division. I've been quoted a few times on here in some of the other parts of the forum about what a great gun it is. I wore out 500 pieces of federal 10 mm brass (over several years) before I had it worked on for competition. Currently it only ignites Federal primers with any kind of reliability but it has a very smooth 5.5-6 pound double action pull. If you keep it stock, you will be able to light off any kind of ammo with it, obviously.
I chose to go full competition since I already owned a couple of other 40's. I like the ability to be able to shoot the same ammo (and load the same ammo) if I so desire.
The gun can be very accurate with just about anything you feed it. For competition I choose to shoot round nosed bullets, currently Bear Creek Moly coated 140 gr bullets loaded to minor (~1000 fps). I had loaded the same bullets to 1350 fps with Power Pistol and while they were snappy, they were very accurate out to 50 yards or so (didn't need to shoot past that). I imagine they can be equally accurate with jacketed (pricey) or moly/plain lead at higher or lower velocities.
Accuracy doesn't seem to suffer in using the shorter 40 cal cases as opposed to the longer 10 mm cases. Since the latter is harder to find and expensive, loading the 40 S&W long seems to not make much difference to the gun. With heavier bullets, you can load them to 10 mm length and still have good accuracy. The 140's being short I tend to load them to about 1.175".
May you have a lot of fun with that one, I certainly do.
Something I wanted to add, if you want to not use tools to moon and de-moon your brass, I highly reccomend the RIMZ Polymer moon clips. No tools needed and they have enough "Meat" so that you don't need worry about them coming loose from the clip. After a bad experience with a metal moon clip, I pretty much stopped using them for competition due to them screwing me up on a fast reload. The Moon clip was bent ever so slightly but undetectably until I threw it into the gun and it siezed up on me. The RIMZ moons don't do that.
One other thing.. I tend to go up to about 2000 rounds between cleanings and the gun, while the cylinder is so dark it looks like a titanium cylnder, never has a hiccup. That is usually about 2-3 months of practice and matches.
