The gun (it is a Glock based gun, but I was contacted by Glock and asked to call it a pistol) is actual size, and is a fun gift or fancy dress accessory.
It will look quite realistic, so please be careful with it. It was made for fun, not as a political statement or anything else. I had an air pistol that I copied. There was no more thought than that. In the UK we don't really have a problem with guns, so I am sorry if my American friends are offended, it was unintentional. Anyway, I didn't crochet any bullets so it won't fire.
