How many shots have you fired in the past?
I have been carrying concealed since 1992 when I was stationed in Florida. So that's 23 years between Arizona, Texas, and Florida.
In that time I have carried in order:
Browning Hi- Power 9mm
Glock 27 .40
Springfield 1911
Glock 17 9mm
Glock 29 SF 10mm
Since about 2008 I got sick of carrying bulky firearms and magazines.
I mostly carry either a Charter Bulldog .44, Colt Cobra .38, Ruger LCR 357, Beretta Nano 9mm or Keltec P3AT 380. ( and a few other misc ones I tried and got rid of) All Lightweight.
In that 23 years of concealed carry, I have never had to draw and or fire my firearm.
I did however need to use my house gun around 93ish, the Browning HP at the time, to stop a home break in by two misguided south floridians whose lives apparently matter more than mine lately. I fired a total of one shot. They found the bullet later sitting in the rib cage of youth #1 who on pure adrenaline made it three blocks from where I lived. Youth #2 disappeared into the concrete jungle.
If I was on duty, where I had to go into the danger every day, you bet I would carry a hicap such as a Glock 17.
But as a civilian I practice certain things and it keeps me pretty clear of trouble. I wrote about it here:

The panic lately has been ISIS, active shooters, oh my god!! Honestly you have a better chance of getting attacked by a dog or a misguided youth. Or dying on the way to work in your car. I won't live my life by fear. That's what they want. I will probably get hit by lightning first.
When I am rural (where I live) I always have a rifle in the truck with me. Especially when I am on my second property which is way out in the boonies. Why? I live in rural Arizona, you just never know what meth lab, drug deal, coyote, or other miscreant you are going to run into down the next wash or over the next hill thanks to the lax border policies. Now the armed lookouts are operating as far in as 100miles.... that's the official word I bet it's more. A lot of people on the run end up in tents or RV's out in the desert here because contact with LEO is rare. The desert is a perfect place to hideout. A rifle is much better than a handgun in those situations. I have had my encounters with some shady people in the desert that made the hair on the back of my neck stand up. I am more worried about them than ISIS or active shooters off their prozac. Glad I had a rifle with me just in case. Thankfully I never had to use it, but now with the new magazine capacity laws, I can do some yote hunting as an added bonus with my self defense rifle without having to carry a lo-cap.
So in my opinion, if you practice and train with your 5. Are proficient, not only at the static range punching paper, but also one handed on the move then I think you are as dangerous if not more dangerous than the guy who carries a hicap and practices maybe four times a year two handed and stationary. You are never too old to take a force on force class or a low light defensive pistol class that incorporates movement. My dad took them with me from time to time before he passed. He was 70 when he took his last one.
