As a Texas CHL Instructor, I have to qualify with both revolver and pistol every other year. I think I've used different guns every time I've qualified, starting in 1995, but I don't remember everything I've shot! For wheelies, I've qualified with a 6" Power Port 686, a 5" 625, a 3" 681+, a 3" 696 and a 2" 15-3, as I recall. For autos, I've used a Glock 17, a Glock 35, a Kimber 5" 1911, and last time, my frequently carried Nighthawk 9x23 Talon II Bobtail. I think I shot a Glock 23 one time, also. The Texas course is so easy, of the 14 times I've shot the COF (7x 2 guns)which would total 3500 possible points, I think I've dropped a grand total of 5 or 6 points, usually because the guy on my left had a Ruger P89 or the like, whacking me in the face with about 2/3 of his hot empties.
Almost forgot, loads: For the revolvers, I used .38+Ps in the .38 and .357s, Blazer 200gr. Gold Dots in the 696, and Federal AE ball in the 625. In the autos, I used whatever factory ball I had on hand in the 9mm and .40 guns (likely Federal AE or WW White box), Federal AE 230gr. ball in the 1911, and WW white box 124gr. JSP in the 9x23.
