[quote="Beginner's Guide To Carry
The first thing to learn (which will be demonstrated later) is that in regards to concealed carry, everything is a compromise. You sacrifice caliber for capacity or overall size, features for cost, sight radius for concealability, etc. Get used to this concept now as it will be a factor in every decision you make from this point. There is no perfect gun, there is no magic bullet, and despite my best efforts (in this message) there is no one size fits all.[/quote]
