Question: do i need to buy anything else for this gun.  i.e. co2 cartridges?
Document: I've had my 717 since the mid-1980s, and thanks to regular lubrication and care it still shoots as well as it did new.The only inexpensive match pistol I know that's significantly better is  Daisy's ownDaisy Avanti 747 Triumph Match air pistol, which adds an adjustable trigger, a better sight, and a Lothar Walther barrel. That gun may be an even better buy than the 717.
Very quiet easy to shoot all day long.Great Adjustable trigger.One of the Best Air Pistols I ever bought.Yes its recoilless with nice front and rear sights .Buy from Amazon and save !
I spent a lot of time researching .177 pellet pistols before I bought this one. My priority was &#34;accuracy&#34;. I didn't care about fps, power, distance, 'cool factor' or any of that. I was not looking to kill anything (although I'm not opposed to reducing the rat population if the situation arises). I live on a lake and am just interested in plinking, target shooting, and hitting tiny pieces of floating debris as it flows downstream.
While this air gun is very accurate and fairly easy to use, it's aggravating to have to reload each round. It has a firm pump. I will keep it, but it's not what I was looking for, a non-lethal way to discourage critters around the house. In fact, I'd say this air pistol is quite lethal!
The gun does well with all kinds of ammo, but I get the best results with my preferred pellet, Mount Star Jets. Even after 20 years, the black finish looks great, and shows no signs of corrosion. The only issue is that the pump lever is a little loose, and occasionally swings out.I'm not into match shooting, so the ultimate value of this gun lies in its remarkable durability and solid accuracy.
I bought a Daisy "Powerline 717" air pistol, sometime in the early 1990's, and some 20 years later, the pistol still works well, and remains pretty accurate, with very little maintenance besides the occasional application of a little oil.Externally, my gun looks a lot like the "Avanti 717 Triumph Match", as the newer model has retained the older designation of "Powerline" on the barrel.
Got a new 717 in July 2013 & really love it. The newer model is the very same gun as the 747 except for the Lothar Walther barrel & even comes with the 747 manual. It has the same adjustable trigger as the 747 from about 1 to 4 lbs pull, it is a single stage & no creep, really great. It chronys out at 390 fps with 7.4 grain pellets.Daisy's customer service is second to none, they really care!
Shooters with much greater skills than mine, have apparently been able to do wonders with the gun, as there are reports of the 717 shooters, besting those using European precision air guns.The grips are plastic, with a thumb groove that I find really comfortable. My hands are not large, and the location of the trigger is set close enough, so that I don't have to stretch out my index finger very far. I was even able to add a trigger shoe, for better control.
A nice feature for beginners and younger shooters, is that the gun has a partially shielded safety, and also has virtually no recoil. While it's not the best or most accurate air pistol I have owned, it is by far the most reliable.The 717 has a fully adjustable rear sight that is solid and hard to displace. When you aim, the front sight is very easy to acquire and line up. Because the front sight is a bit wide, I personally have difficulty achieving "target class" accuracy.
I purchased one of these single pump target pistols 25-30 years ago. I wanted teach to my son gun safety that I learned from my father. This pistol is very accurate and cheap to shoot. I have an indoor range in the basement. My son and I spent many Michigan Winter days shooting in the basement.I dropped the pistol on the floor and broke the rear sight. I called Daisy looking for a new rear sight. Daisy sent me a new rear sight at NO CHARGE.
