I took my initial CHL class at Bullet Trap in Plano and I will not go back there. Did not like the instructors presentation or the fact that I had to come back another day for the range portion. That was over 8 years ago, maybe they have straightened up some, but, I kinda doubt it.

Concealed Carry Institute in McKinney is a good couple of instructors (LEO's). I took my 1st renewal there and will probably go back next year for my 2nd renewal.
They teach you what you need to know and do not talk down to you or give out any misinformation. Their range is a small PRIVATE outdoor range just West of McKinney. There is no charge to you for the use of this range when you are in a class.

Red River Firearms Range in Sherman is a really nice and clean indoor range. I shoot there often. I believe at least one of their instructors is a Deputy Sheriff with Grayson County S.O.). I may end up taking my 2nd renewal there next year (instead of McKinney) as I am only about 15mi from there and their price is comparable.
