IF that gun shop is asking less than 1500 dollars that is a STEAL. Fact is you could probably flip it for 2000 dollars or more. I have a 6 1/2 inch 610-3 and still regret not having the wisdom to purchase a 4 inch version at the same time because I only had to pay for my 6 1/2 incher brand new.
As for shooting properties, the only thing I've used in mine is 40 S&W and even with the "bullet jump" due to the shorter case I have still managed to produce 2 1/8 inch groups off a rest at 35 yards. BTW the long range indoor range I shoot at has the targets well lit at 35 yards but 25 yards is rather dimly lit and 50 yards is decent if you bring the target forward about 2 yards. As a result when I'm testing a handgun for precision I use 35 yards even if it's a bit of an oddball distance.
