The Crosman is nice and cheap, buy it now to scratch the itch and maybe move up to a HW45 after a bit.
I have both, the Crosman is what I am shooting a lot at the moment, the HW45 has not been out in a while. Both are great pistols but the Crosman is so much more accessible as a first pistol. If you do start buying pistols then you will end up with an HW45 eventually anyway.
I don't find the Crosman totally recoilless though, there is a distinct muzzle flip straight out of the box. Any mods that up the weight soon sort this out (though it might be psychological or bad form on my part).
Great Deals with : Dave Dee, Dozy, Beaky, Mick & Tich
