My 'if they take it' gun is a .380 Makarov inexpensive enough not to feel to bad about losing but still potent enough with my Hornaday XTP handloads. I would feel much better with my Hi-Power but I'm not willing to lose it. 
@GtHawk The easy question to ask is "Which do you fear losing most,your life,or your Hi-Power?"
The truth is if you can keep your cool and aim,you can kill an attacker with pretty much anything. I would PREFER to be carrying my 44 Special if "push ever came to shove",but I am confident that a 22 LR Hollowpoint from my 9 shot 22 revolver into an attackers' eye socket will settle his hash nicely.
If he is within 10 feet of me,there is at least a 90 percent probability of that happening. If I miss,I hit him in the forehead or cheek.
With the first shot.
Truth to tell,not really being a "sporting person",I would prefer to be carrying my 12 gauge,but it's a little awkward to conceal. I only prefer the shotgun because calling in an air strike on them is no longer possible for me. Like I wrote above,I am NOT a "sporting person".
