I bought a "supplemental" concealed carry gun......
today. I will start practicing with it starting tomorrow. I don't intend it to replace my Kel-Tec P32 front-left-pants-pocket gun (with a cartridge in the chamber). This will be an additional gun in the right-front-coat-pocket. I won't always have my coat on, but when I do, it will be close at hand. I have checked and it will fit easily in that pocket of any coat I own.
The new gun is a LNIB S&W 642-2, 5-shot, 38Special, airweight, covered-hammer, J-frame with a 2" barrel. I would have been able to reach it in the situation described previously.
Between the two of them, I should have something I can reach in the future.
