Hello Mate,
Have had a HW 45 in both .22 and .177 flavours and liked them both,
They are not a cheap item so it may be best to try one of someone else's before buying, not everyone gets on with spring guns,
A club is your best bet, most are very friendly and will help you out,
It all hinges on what and where you shoot really, there are many pistols out there,
I live in Leicester and shoot at a Pistol Club and a Local Rifle range,
Look at where people are located and ask about their Clubs if they are near you,
Hope this helps,
Bernard.
