I have experiment shooting with all kinds of competition air pistols. One of the best air pistols are Steyr, Feinwerkbau and Pardini. I prefer Steyr LP10 as you can see a photo below. It has an excellent two-stage trigger. You can refill either CO2 or air into the aluminum cylinder. It will hold up to 200 shots. The barrel is unbelievable. It is very accurate. It can shoot the same hole all day at 10 meters/33 feet. It is good for indoor range. To me, it is a long range for air pistol. The rules are you must shoot 60 shots under 1 hr and 45 minutes. The score would be out of 600 points. The 10 ring is about the same size as your fingernail. One wrong movement will put the pellet, .177 cal out of the target. -Denny Guinn P.S.
