The STI Duty One pistol is about as realistic as you can get when it comes to 1911 air guns. The slide moves just as it would in a firearm. The air pistol is even better than the firearm...because you get 20 shots from a mag!
If you like the 1911 frame and can't get to the range to practice with your firearm, this gun will go a long way toward helping you maintain proficiency. You'll also save a lot of money by shooting steel BBs instead of live ammo.
Steel BBs can ricochet. The shooter and everyone in the shooting area should wear safety glasses when a gun is being handled (even if it's unloaded). Remember to remove all pets from the area, as rebounding ammo can hit them, too. Never shoot steel BBs at hard objects (including metal targets) or water, as that increases the chance of ricochet.
