I have an easy program to help you conceal a handgun, it has worked for me so far:
Eat a lot
Don't excersise
Gain about 130 lbs from when you were the fittest
Then wear a button-up 3x shirt in whatever kind of holster you want with whatever kind of gun you want. Never prints, and you never have to worry about some hottie coming up and hugging you unexpectedly as you now wiegh 300 lbs!!! But that is just how I do it, being trully dedicated to concealed carry and all.
