Type: Pellet air pistol. Manufacturer: Xisico. Model: XSP180. Materials: Metal & plastic. Weight: 2.5 pounds. Barrel: 9.1 inches, metal-rifled. Propulsion: Spring piston. Action: Single shot. Ammunition Type: .22 caliber pellets. (Also available in .177 caliber) Ammunition Capacity: 1 round. FPS: 400+. I wasn't expecting the world from this spring piston break barrel pistol because it is a more price conscience gun and yes it may not be as refined as the Webley Alecto I also reviewed but I have to say it performed well and exceeded my expectations in most every way. First off, when the manufacturer claims 400 fps from the .22 caliber version this usually means the absolute best case scenario! I used medium grain pellets and still got some amazing chronograph results from this spring piston shooter right up into the 470 fps range. Secondly, being a springer with a heavy recoil, I figured it would effect my shot placement but again I was surprised and shot as tight a group as I can expect from any pistol with open sights from 30 feet out. lastly, again if you can get your head around the plastic, this gun feels well made and I would expect a lot of good times shooting with it for many years. If you're on a bit of a budget but want a compact shooter you can target shoot with or even take down small to medium sized pests, then grab yourself a Xisico XSP180.
