So I am just getting into the world of gun ownership and at this moment the only firearm I own is an antique piece. I want my next firearm to be a modern handgun, either semi-auto or revolver is up for discussion. I want to make sure it is a "do all" firearm though. Something I can use for home protection, woods carry, and mere target practice. I am stuck between a M&P .45, Glock 20, or the M&P R8. There are a few others but these are the most likely. Now I understand shooting the G20 is expensive but I have heard with a simple barrel swap you are shooting .40s instead of 10mm. And before anyone tells me to buy a 9mm let me restate I want a "do all" firearm. If anyone has experience, good or bad, with these firearms let me know what you think. Also if you have any others I should keep in mind feel free to respond. Please do not respond unless you have at least owned or know someone that has owned the gun before.
