I have 3 guns that I regularly carry concealed. Obviously not at the same time. I train with all 3, I'm proficient with all 3. They all shoot mechanically basically the same: "All SA/DA". I feel just as comfortable with any of the 3 guns. And I never consider what I'm wearing. Between the 3 guns, I can wear literally anything. And I do. From shorts/t-shirt and sandals, to a tuxedo or similar suit. All the way to winter days at -20 and heavy coats. I've never changed out a shirt, pants, jacket, or anything because of a gun I was carrying. Then again, I don't believe that I need a gun with a 15-18 round magazine like some do. I also train and believe in shot placement. Been training that way for almost 40 years; civilian and military. So I have no problem carrying a 32acp, 380, makarov, 9mm, or 45acp. And I'm willing to carry just the magazine that's in the gun.
To each their own. But I have seen first hand people who have gone over the edge. Their lifestyle has totally changed since they got their concealed weapon permit. They've all of a sudden developed a paranoia that apparently wasn't there when they didn't have a concealed permit. These people would come to pool parties or similar. They'd ride bikes. etc... Now however, if they can't have and keep hidden their full size pistol, they feel like all of a sudden they're going to be mugged or shot at. I understand where they might be coming from, but when I suggest they get a 2nd gun, such as a small 380 or 9mm, which they can put in their pocket or a small IWB type holster, they won't have anything to do with that. I swear, I know 2 people who have gone so far over the edge, if they could find a way to make a 460sw into a 15 round semi-auto that they could carry concealed on their body somehow, they'd try for it.
Anyway, there's nothing wrong with a 1911A1 pistol. I love my kimber and my Springfield. I don't conceal carry them, but that's my choice. I do at times carry the sprinfield open carry when I'm working at my friend's ranch or that type of outside activity. Then again, I carry that gun in condition 2. "Another topic all together". No, I have 3 guns I carry concealed. And they are all basically clones of each other as far as operations go. All SA/DA, all have a de-cock, and all shoot pretty much the same. And I can dress any way I want or participate in pretty much any activity I want and not have to worry about carry concealed.
