Sorry that you had a bad experience there. I dont know all of the employees, just one or two. There are always going to be blowhard "operators" at gun stores. Lol. Keep an eye out on here for Coye knives and they only go for a couple hundred here. Good luck man
I have a Tactical Assault Gear (TAG) vest that I like. Holds eight mags and has molle to attach whatever else you want to it. Probably wouldn't work as well for 3gun. I have it loaded next to my Go bag.
My first gun was a Kimber Combat Carry. I bought it from a friend of the family and got a great deal on it. Its a great gun but I don't shoot it much anymore.
