I will be purchasing a handgun for self defense. Now, my delimma is what to buy, if I go with a modern handgun, I will be limited to vehicle (already have a locking gun case for my car) and private property carry. For modern handguns, I have narrowed it down to these choices : glock 17/19, canik tp9v2, s&w m&p, or a s&w m&p shield. I regularly go with my dad to the range to shoot his duty glock 22, as well as his off duty m&p shield .40 and I absolutely love both of them. (Although my wallet would prefer the shield). Now, if I want to carry, either on my person or in my bag with the ccw pocket, I would be limited to a cap&ball revolver. Now I know this suggestion is usually frowned upon, but although old, they put plenty men 6ft below in their hayday. A .44cal conical moves as fast as a .38sp and hits alot harder. If I get an 1858 new army, cylinders can be swapped as fast as a modern revolver can be reloaded. Now, a good 58 new army is the same price as the m&p shield, given my options, what is your opinion on what I should get? I ask that you keep in mind, I am going to purchase a firearm, this is not a hypothetical question. My parents support it, and I belive that carries weight given my dad has been a police officer for over 10 years. I simply need imput on which firearm.
