The .22lr isn't much of a weapon but it's excellent for small game which is what we have here in the UK. It's lightweight and can be properly silenced with a sound moderator rather then just reducing the noise. It's only drawback is also it's great virtue, it is so low powered that it doesn't mess up the meat.
If you wanted to use one as a weapon I suppose you could use it as a club and beat someone over the head with it
