Things I liked:Quality, sights, trigger, accuracy, the way you load CO2.
Things I would have changed:The way the grip is held on. It some times comes off, when you set it down.
What others should know:Hi there. I bought this 586-8, to practice one hand double action, bullseye shooting. I have a Crosman 357-6. The weight of the 586-8, is double that of the Crosman. For me this is fine, but it may be an issue for some. I bought it a couple of months ago. Since then, I have put over 2000 pellets through it. At first, I wasn't super happy with the trigger in double action. But, it keeps getting smoother. I'm very happy with the trigger now. The gun came in a nice hard plastic case. It came with a barrel wrench (you can buy a 4" and 6" barrel for it). Check to make sure the barrel is tight. Mine was a little loose when I first got it. I've only been shooting it indoors, so I haven't chrono it. The gun also came with 3 front sights. They are the same height, but different thicknesses. They are easy to change, and allow you to adjust your sight picture. I'm shooting it at about 28 feet at a NRA 25 foot bullseye target. One handed, I'm keeping most of them in the black. Out of twenty shots, I'll have about 3 out of the black. The farthest I can shoot it in my house, was 38 feet, from front of gun to the target. I leaned against the wall and shot two handed single action. I was able to get a group just under 1 inch. I was using Beeman 7.2 grain Hollowpoints. I can get 60 full power shots, all the time. After that, it might go 70 to 75 before the power drops off fast. The gun comes with two 10 shot cylinders, they are made of metal. They feel heavier than aluminum. Blaine
Things I liked:Most every thing, accuracy, weight, workmenship. It's true quality. I wish my FNP 40 autoloader was this accurate. I normally shoot at 25 yds. and this gun will shoot a 2 inch pattern with high quality pellets. I get a good fifty shoots per co2 cylinder, after that the power really deminishes. I purchased the 6 inch barrel and extra mags. The 6 inch barrell doesn't have the accuracy of the 8 inch at my normal shooting range of 25 yds., but at 10 meters you can hardly tell a difference in the accuracy. The gun is a bit pricy, but due to the quality and accuracy I feel I made a wise choice. Also, dealing with Pyramyd A/R Gun Mall was an absolute pleasure.
Things I would have changed:Would like optional wood grips and fiber optic sights.
What others should know:I purchased a white paint from a gun store for placing white dots on the sights. It really helped my sight picture. The paint is available in different colors and some will glow in the dark. Finding a holster was easy.
Things I liked:Awesome heft, feel and accuracy. The gun is very heavy, but feels good in the hand.
Things I would have changed:the grip that pops open for inserting the CO2 cartridge sometimes pops open when you're firing. Also, the rear sights tend to go out of alignment easily.
What others should know:Great gun, you'll be going through pellets like crazy.
