Comfort is very important for those that are carrying 8-10hrs or more a day. I’ve carried various firearms over my life and sometimes it’s fine carrying something Monday-Friday, but if I’m still carrying it on Day 6, I can really feel it. I’ve found that driving in a car for long periods of time can really make IWB and paddle holsters feel annoying after a couple hours. I can use an ankle holster is some situations, but I’ve found that the most comfortable way to carry a full size auto for long periods of time is in a should rig. Leg holsters are probable a 2nd favorite, but that’s not going to work for concealed carry purposes. One thing to always be aware of is not sweeping body parts when pulling a firearm in the seated position while wearing a should rig.
There are so many methods of carrying a gun, but no firearm or holster is going to do it all. Nobody carries a airweight 38 special in a leg holsters and it’s not a very good idea to carry a Beretta 92FS in your pocket, even if you can. I’ve changed my thinking when it comes to CCW and the caliber debate. Some of the best self defense instructors I know carry the smallest caliber firearms because they know that situational awareness is the best defense and if they have to deal with a threat, a good shot in the right spot is all that counts. One method of carry that seems to be bashed a little too much is the shoulder holster rig. These gun holsters may not work very well for some body types and for warm weather because I admit it is easy to pick out the should straps if the appropriate clothing is not worn.
