Mine is my Beretta M9A3:

I grew up in South Louisiana, so I know what you mean.Mine is a Stainless Steel AMT Hardballer .
Back in the day no one made a stainless steel 1911 , not even Colt ...
Living in Louisiana , the land of Heat , Humidity , Hurricanes and Rust ... my 3 blued steel 1911's all suffered ... seems my very touch of a sweaty hand induces rusting and was a constant battle to keep the finish on them ... The AMT announced an all stainless steel 1911 , with Millet fully adjustable sights no less ...
My prayers had been answered ... my dealer ordered me one in 1979 and I've cherished it ever since ... it's sitting on the desk next to me right now .
I have never had any trouble with it , I was told to grease the sliding SS parts with Lucas Red-N-Tacky Lithium Grease to prevent galling of early stainless ... the bugs hadn't yet been worked out and early SS liked to gall and drag ...
That info was spot on ... all the other 1911's are gone but the Stainless AMT Hardballer just Keeps On Keeping On .
Sorry no photo but my camera is broke ... wish I could show off the Ahrend's Ebony grips ... Kim Ahrend told me the Ebony wood was his favorite with stainless pistols ... and he's right !

All metal Baby Desert Eagle in 45 ACP! Solid, accurate and as deadly as you get. Depending on the powder, I clean it after about 500 rounds.What is your ONE favorite metal handgun (no polymer frames)?
