Dirty Harry Model 29. Every time I thought I had enough money a new Harry movie came out and jacked the price up.
Quigley down under a sharps.
Jeremiah Johnson a "Hawken rifle 50 caliber or better."
Cold Mountain a LeMatte revolver. The large smooth bore barrel and nine shots intrigued me.
Those are my top 4.
In reality just about every realistic gun movie I ever saw has made me drool.
