I have an HW45 in .22 & a Webley Tempest in .177.

They're both fantastic pistols. The HW45 is a bazooka that's a lot of fun, the Tempest just a lovely British plinker that's also heaps of fun.

As a first proper air-pistol I'd get the Tempest (it was what I got), you can shoot it all afternoon & it'll make you smile . The boxed .177 mentioned above looks cool & to be honest if I didn't have one already I'd have bought it myself by now
