I carry a glock 21 every day. Including my time at work. I also have an hk usp 45 but due to some sentimental value I don't carry it. I know I know it's made to be used but I just can't bring myself to carry it. Believe me it gets used at the range haha.
I carry either a Kel Tec PF9 or a Ruger SP101. Both in an ankle hoslter on the inside of my left ankle. Tend to carry my PF9 more because it is quite a bit lighter!
I usually pack my Ruger LC9 but like to switch out occasionally to the Tressitu TZ99. Would love to pick up an AK pistol for cold winter days when I wear my big warm coat tho. Or just as a truck gun.
For concealed purposes I choose my Ruger SR9c. If I am wearing a jacket and not necessarily doing anything but shopping I choose my Sig Sauer P226 Extreme .40. I use a blackhawk holster for it.
