Almost two years ago I bought and shot a 9mm for the first time. I was impressed with this little cartridge, pretty darned powerful. My first pistol was a PF9 and it shot well but I got hooked on shooting at the range (again). After 1200 rounds I decided that I should get a full size 9mm so I bought a Sigma 9mm. Shoots very well and lot easier on my hand. I like it.
I joined several gun forums and there I discovered a 40sw. A high pressure round like the 9mm and snappy recoil. I thought hmm... I want one so last April I bought a Sig P250c in 40sw, my first 40sw pistol. I like it.
So there they are, my two fav calibers.
I'm not new to handguns. I used to shoot back in the 80s at the range (same place) and I had 22s, a 25, a 380, a 38 super and a 357. Never had a 38 special nor a 45.
