Agree. Carry the gun you have the most confidence in. That means if you shoot a 1911 in IDPA but carry a Five Shot Snubby, there is a disconnect. If you are only going to carry the snubby, shoot it in IDPA or however you train. Most guys do not shoot a J-Frame much, but it is the one they carry the most because it is so easy.
It is a lifestyle. That is the best, shortest, most succinct description I have heard. I carry a 1911 now that I am retired, because I carried one for decades and it is the platform I shoot the best. I dress around it, inside the waistband, and have for years. I don't wear a T-shirt and jeans or shorts, because that may be comfortable but I can't hide anything dressing that way. My shirts have buttons and collars. I have learned to live with it.
