SA Friday, Copy all.
Most of my Glocks have the .100 wide front sight. I find this to be a pretty good compromise and I can keep pretty fast splits when shooting a multiple shot string on one target. I've got one pistol with a .125 wide front and it's a laser for precision (avg. high 90s on a ten shot string into a B8 Repair center at 25M) but not as good if I want to run fast. (fast being a relative term based on my skill).
I'm a big believer in quantification. If something is "better" that should be verifiable with data. For shooting I want faster and more accurate so a shot timer and B8 repair centers are the order of the day if I'm going to decide something is "better".
I'm going to try taking a paint pen to a front sight and see how that affects the splits on target to target drills. I've never liked the FO front sights because I've seen several guys lose the FO insert but I may have to give them a try and see what kind of difference it makes.
I'm not trying to beat the race gun guys. But if there is a way I can cheat a little with my carry or duty gun I'm going to be on it like a fat kid on a cupcake. The catch is that it needs to be able to hold up to the abuse that a carry or duty gun will sustain.
