My first was a Rugar MkII. I think I spent around $200 on it. It's still one of my favorite to shoot. I used to love shooting pin matches with it at SVGC until they stop having them.
My first handgun at age 12 was a 1851 Colt Navy .36 replica bought new for $39.95. My first centerfire handgun was a Remington Rand 1911A1 at age 14 for $150. Needless to say thats been a few years ago.......
