welcome to BBS,I have 2 HW45 PISTOLS .177 and .22 they are both great pistols for hitting tin cans etc it will take you a while to hit targets every time because of the recoil ,you may want to consider fitting a red dot sight at some point ,I also have a webley tempest but prefer the HW45,you have made a good choice,although I prefer rifles for target shooting but as you say with todays advanced rifles it is very hard to miss the target a pistol is more of a challenge,have fun.
