If you're still looking at the desert eagle, there is a nice metal slide version on RedWolf:
KWC Metal Slide Desert Eagle
It's the first one at the top. I can't comment on the quality as I have never owned it. But if I were you I would go with a 1911 of sorts (I'm a 'big gun' guy myself, plus I like the classic style) like this one:
WA S.C.W. Ver.3 Colt Government M1911A1 Military
Once again I cannot personally comment on the quality of this gun, but one of my buddies owns it and it hasn't failed him so far.
