I am a firm believer in the statement "Perfect Practice Makes perfect". How much do you practice your EDC guns? What distances do you practice from? My main carry guns (Glocks) get about 200 rounds a month spread over the 3 of them. My BUG gets about 100 a month. They are not all carry loads, I can't afford that much factory ammo.
I usually do about 1/2 of that square range and 1/2 during IDPA matches. I believe in running my carry guns. I am under no illusions that I will ever win a match, but it is fun and it is practice running my guns and reloading under simulated stress. What I really notice is when people have a malfunction (myself included) it takes a second or two just to realize it, then it is usually cleared within another second or 2, you may be out of the fight for 5 seconds. I think that is something to practice and prepare for.
I try to limit my range sessions to about a box of ammo, after that I may start to get sloppy, I do not wish to practice sloppy moves. Dry fire is an indispensable practice method. I dry fire daily when I don't get to the range.
