Do you own a blue gun in the model of your carry gun? If not, you might want to consider it. I own 3, actually. I have found them to be irreplaceable for training situations at home. Dry Fire in a controlled environment is important, but there are things I want to practice where I don't want to be in my controlled environment, which is quite limited.
I use my blue guns to try out holsters, to practice drawing. I play a game with my husband where I will be wearing a blue gun just like I would my carry gun and he will call out "Threat" and we see how long it takes me to sweep and draw. It is one thing to practice a fast draw when you tell yourself in your head "now", quite another when someone else calls it out, even when you are expecting it. It has made a big improvement in my reaction time.
I can roll on the floor, I can beat on my heavy bag, "escape" from it and draw on the move. All in complete safety. I don't feel comfortable doing that with my real gun.
Don't misunderstand, a blue gun is not a toy, it is a tool. For me, it is a tool to inject a little reality into my practice and help me build skills I hope I never have to use.
