I might diversify to 9mm too. I will carry a .45, because I think it's best option for me. However, I'm genuinely torn between and FNX45T and the 509t for my boog pistol
The 45T was all the rage a few years back. Other than the bendy frame I haven't heard much bad about them. The 509 I know zip about. What's weird is as well known as FN is for their rifles they can hardly give pistols away and they're largely under the radar.
