The first firearm I ever bought is a mossberg 802 plinkster. Bolt action .22. Bought it when I turned 18, for $110 after tax. Has gone everywhere with me, I own a fair amount of guns now, and I still find it fun to shoot, and still accurate. It has iron sights. One day might throw a cheap scope on it for fun.
First handgun was a Taurus 24/7 pro ds in 45 acp. Bought it because I could afford it. Shot well and did what I needed it for. Traded it off for a SKS. I do miss it as it was my first pistol, but I like the SKS.
