Well gee, i've only shot maybe a dozen different handguns in my life. I only currently own two with access to another not owned by me. I really enjoyed my AMT .22 lightning target pistol in my youth, but my XD45 has been lots of fun & really fits my hand well. The snubby .38 wasn't meant to be liked, only used & then only when really needed.
So, XD45 with the 5" barrel would be my choice, currently.
