 different types of classes for advanced training and such. And then I found other types of carry sizes that work for me. And some of them are color and some of them are not. So it's kind of like, hmm, what am I going to wear today? It's like an accessory. So if it's a baggier shirt, I might wear the bigger, smaller gun, if you will. And if it's a smaller purse, then I'm going to go for the smaller carry gun.
