RE: Any opinion on the Glock 20, 10mm?
Read up on the F.B.I. firearms history. they where the first law enforcment officals to use them. and the first to stop also! I would recommend the 40 cal. ( after all it is derived and improved from the 10mm) above all for personnal defense and fun in shooting. Now I personnly dislike the glocks tremendously. I have freids in law enforcement with me who swore by them at one point but then all ( but one) changed. We mostly use the sig sauer p229. Great gun, very reliable and talk about low maintenance. It's important to remember that a pistol is an extension of your arm so be very comfortable with what ever brand you choose.
