When I came across the Pedersoli Derringer Guardian #11 I just had to have one! Heck, it's a pellet gun, and It's kind of a blank gun or cap gun all in one, it's also one of the smallest pellet guns I have ever seen. Like most of the other pellet pistols I own, it does not require a PAL or Firearms license here in Canada and can be shot in a lot more places than a "real gun" or Controlled Firearm can because of the low energy levels it produces and of course lower volume of sound it emits. I suppose it could even be shot indoors if you had the right setup in your house or garage. Definitely one of my most unique pellet pistols I own.
