The first handgun i shot was my dads first hand gun, a 357 magnum, aka 38 spl.s were being shot mostly but the 357 was so much fun, the next time I shot a 22 hand gun it left me feeling kind of bored and it felt pointless to me since there was no power to me, but I have been shooting a beautiful 22 rifle for 15 years so in a hand gun it seems pointless to me. I have since shot a .45 acp and find it a thrilling gun to shoot as well but when it comes to making my first purchase, I will be buying a brand new Glock 17 3rd gen with laser sight, 5 mags , belt, hoster, mag pouches and 500 rounds for $1000 even. With a deal like that Im very excited to get in in the next couple weeks... Getting 500 rounds for $120 buck isnt a big deal at gun shows its sometimes cheaper than that so for only 5 times the ammo price, and half that of all other calibers it seems the obvious choice. Especially since I can fully strip the gun into what 6 or 76 pieces in its entirety and put it back together in 15 seconds? I'm no gunsmith so its a big plus for me.
This is all my opinion and what feels right to me but its all related to my life experiences and what felt good in my hands so if somethign else feels better get it.
