OK, I’ve got some questions about the P3AT before I purchase one for back up carry purposes. The PF-9 has exceeded all of my expectations and I’m beginning to consider it the cat’s meow for off duty carry, to the point my Glock 27 might be going into hibernation mode in the safe for a while. The only thing about the P3AT that I’d like to determine as feasible is widening the rear sight grove and putting a larger front sight on it. Widening the rear sight grove is feasible, I’ve seen it done, but the front sight has me perplexed because it would have to be readily to the shooter’s eye but still be small enough not to hinder gun concealment. Anyone tried out something that they liked in a modification such as this? Also, I haven’t dissembled a P3AT so I don’t know if a grove could be milled across the front of the slide for a drift in front sight or not.
