Should I buy a glock 19, a xd compact a cz P-01 or a fn pistol all in 9 m.m.??? I think the cz will shoot the best groups from the reviews I have read,but parts are more expensive.Glock magizine is half the price of a cz.The cz is the only aluminum frame.The fn is a little more expensive.The cz has a 5 year warrenty.Glock and xd lifetime and I don't know about fn.I have a 38 snobnose for carry so the size and weight is not really a factor, nothing carry's as good as a snubnose 38 aluminum frame revolver.
