Glock G20 G4 10m 4.6" 15rd Fs - $579

How do you like the 10mm round? Im a die hard 9mm loyalist.. lol but have been thinking about getting a 10mm for my duty use. I want something with a wee bit more stopping power but do not want a round with too much over penetration and risk to the public.
I am also curious what sort of power the 10mm has against regular body armor? I own a protective services and security company. We watch over and secure large amounts of cash as well as high value individuals, politicians, musicians, actors, Valuable items, and high security industry. You never know if someone shows up to do harm or to steal via a gun fight and they are prepared and wearing body armor. With my Law enforcement background and a total of 27 years in L.E. and security services Ive seen and heard alot. Many situations and stories involving a a laundry list of weapons and gear.... Criminals are much more brazen and bold especially in high value crimes. They rarely follow the "stick up" type thefts anymore. Now its planned, usually involving more than one suspect and they are heavily armed and outfitted. so yes I am looking to upgrade my 9mm side arm. I do carry 870 12 gauge and my 7.62x39 AR Rifle in my cruiser in my electronic lock and cage mount. The same as any police crown vic would have as thats exactly what it is. Its a 2010 retired, fully outfitted P71 crown vic. I do love my cruiser.
