Let me start by saying I was a huge Glock fanboy for many years, a very good friend of mine brought his CZ SP-01 to the range . He told me it was a game changer and although I was skeptical I value his opinion so I gave it a try. It rocked my world and opened my mind to a manufacturer I would never have given a second look to ! It is now about 18 months later and I have never looked back. I still believe Glock makes a great gun , I have just found something I like better. What brand opened your eyes and changed your mind?
