Max, I have the Prosights on a Glock 17 and 19. I have used them through Tactical Shooting Academy 1,2&3. The target acquistion is both quicker and easier than with regular sight picture. I use them as ccw pistols also. I do not think you will find a better sight. They are adjustable for both windage and elevation. Check out the Tactical Shooting site for D.R. Middlebrooks who has won numerous IDPA chapionships with them.
All that you need to do to win is survive!
Thanks for the reply CQB1, I'm actually looking at buying a Kimber with these already on, the thing that concerns me is the slide is machined for these specifically, I can't easily put in a standard sight. I shot the gun with these and after five tables of bowling pins got my time close to my time with standard target sights. I can see the potential to be much faster, just would like to here success stories like yours, thanks Max
