I bought two at once. A Ruger P85 and a Taurus PT92. I ditched the Ruger not long after because it was just too damn heavy. I kept that PT92 for at least 10 years, then one day traded it in on a Glock 23. I have since replaced the missing PT92 with an Italian Beretta 92FS. Every gun owner should own one.
First handgun was a 1851 repro .44 revolver I got for christmas at 15. First hangun I bought was a Ruger P-89 a month after turning 21 and getting out of the army in 1993. Still have it today.
Beretta 92F Compact with Walnut handles. Still have it. Still love it. Bought it 17 years ago from a thug in a plain white van parked on the side of the road. Bought it for $65. I could tell it had recently been fired. Just kidding, but that is the first handgun I ever bought. Bought it new .
