Been carrying everyday for many years Carry a Glock 26 in Khaki pants pocket in a Mic Trigger guard Holster,Factory 10 Round Magazine along with the round in the chamber. Also a Ruger LCP with a Ruger 7 round Magazine with round in the chamber in Propper Blouse shirt pocket along with an extra Ruger 7 round magazine in another shirt pocket. So I feel like I have enough rounds to get me back to my truck. Once I get back to my truck I have a way to escape or an over 5000 Pound weapon depending on the situation.
If you need to engage targets at a longer range Try to have a Rifle as opposed to a Handgun.
