Thankyou for your reply.
I'd kind of ruled out pcp as I don't have a bottle & stuff to recharge it.
All of my rifles are break barrels so I don't mind springers but co2 is an option as I already have a Crosman 2240 which is good fun but no good for targets.
Is the HW40 a single stroke pneumatic?
I'm not a huge fan of air pistols that look like firearms, I prefer them to look like an air pistol, but if they're pretty accurate I guess it doesn't matter too much what they look like.
