Handguns are not meant to be a fashion statement or a after-thought.
They are designed to protect you in a lethal force incident.
If its "inconvenient" or uncomfortable then do not carry any guns or weapons.
Here's a story from my past experience.
I used to use a basic set of hearing protectors that did a good job with hearing protection but not much else. They were uncomfortable and so I would take every opportunity to remove them. Also, I couldn't hear what people were saying while I was wearing them so I'd take them off to carry on a conversation during shooting breaks at the range.
As a result, I was often surprised by the end of the shooting break and would get "smacked" by the blast from several shots before I could get them back on. In once instance, I forgot they were off and fired a shot before I remembered to replace them.
I finally bought a top-of-the-line electronic set and paid another $80 for comfort pads filled with gel. Now I wear them all the time when I'm at the range. They're so comfortable that I don't even think about taking them off and they do their job while allowing me to take care of other incidental tasks like communicating with those around me.
So what does that have to do with carry guns?
The same principle applies. Sure, I can purchase a carry gun that is heavy and large and therefore uncomfortable to wear. I can justify it exclusively in the name of shootability and capacity, ignoring other considerations. Because it's heavy, I probably won't be able to use the urinal with it on my belt--I'll have to go into a stall and take it off my belt to do my business. Now I've introduced the potential for forgetting it, dropping it, having an unintentional discharge--all things that people have actually done with their guns in the bathroom if you keep up with the news.
Because it's uncomfortable, I will also be tempted to leave it at home if it's hot outside and I don't want to deal with a cover garment or if my back is a little sore today, etc.
The bottom line is that the gun is a tool, just like my hearing protectors, or just like the multitool that I carry. One can pretend that all that matters is how well it functions as a tool, but if my multitool weren't small, light and portable, I wouldn't have it on me when I need it. If my hearing protectors are uncomfortable and restrict my activities unless I take them off, there's a good chance they won't be in place when I need them. If my gun is too heavy or too large, there's more chance that I won't have it when I need it, and it raises the probability that in the process of working around everyday eventualities, its deficiencies will increase the probability of potentially catastrophic problems such as an unintentional discharge or the loss of the firearm. It may even induce a health problem such as chronic back pain.
I know that some instructors have popularized platitudes like: "Carrying a gun is supposed to be comforting, not comfortable.", but in the real world, it's a little more complicated than that. Comfort can be a critical practical consideration for a number of truly important reasons.
When you pick a tool, you should pick one that meets your needs, not one that someone else thinks is ideal for you. We are all only human, and as such, we have built in limitations based on who we are as individuals. Comfort is one of those limitations and it's unwise to try to ignore it.
There needs to be a balance. We don't want to put comfort in the driver's seat and ignore any other considerations, but it's equally foolish to try to pretend that we can ignore the comfort aspect of carry and still achieve a workable result.
