Money no object the Steyr LP5/50 is a seriously impressive bit of kit - I had one with a custom silencer adapter and burr walnut detachable buttstock which did for dozens of rats around the chicken pens way back in the day.

5 shots in a couple of seconds, one of the guns I genuinely regret selling.

I now have a Browning Buckmark rifle in .22lr which scratches the same itch but with a bit more poke
