I currently own a Glock model 20 in 10 mm and I've got a bunch of questions. Winchester seems to have the best energy ammo. for the price (I don't reload) in their 175gr silver tip. What do you people think? Are these "full" power loads? I'm looking into getting the 6 inch "hunting" barrel. It comes ported and unported. I've read the 6" barrel will increase muzzle velocity, add stability, and increase accuracy. Is this a bunch of bull? Also, I see notes saying it is not recomended for carry. Is this because of weight? Or increased draw from the holster time or what? They have also said the ported barrels aren't recomended for carry. Is this because the porting hurts night vision and second shot recovery? Finally, I would like to ask about ghost ring sights. I've heard many different things about these sights. Some say they improve target aquisiton speed and accuracy. What do you think. Thanks in advance for your answers.
