If you are shooting properly trigger reset should never be a problem. You should not be trying to time the reset before you start your next trigger pull. You should be letting your finger go completely forward and off the trigger. Todd Jarrett says, "Now trigger control. There are all types double-action, single-action, safe-action, LDA systems on the market. We are going to show you some quick and simple ways to press that trigger to the rear each and every time. The key thing is never try to go to reset when shooting any type of mechanical trigger. You will find that you will be able to shoot any product on the market built today or tomorrow."

Todd knows what he is talking about, his record: Todd Jarrett has been shooting in competition since 1983. He became a full time Professional after winning his first USPSA National Title in 1991. He’s won the Nationals a total of Nine Times—Five times in the Open Division, Four times in Limited. He’s the only person to ever win the “triple crown”, shooting to championship wins in Limited, Open and winning the World Shoot in the same year. And he’s won the Steel Challenge twice. Add all the wins and Todd Jarrett has claimed more than 500 major titles in IPSC competition.
If anyone can find an equally accomplished shooter who recommends only letting the trigger go forward far enough to reset before starting the next pull I would like to see it.
I have the P-3AT and love if for all the reasons already given. My P-3AT is blued. I treated it with Militech-1 and I wipe it down after every couple of days of carry, or after a particularly hot sweaty day, with a cloth saturated in Breakfree CLP that I keep in a ziplock bag. I have never had a problem with rust.
If you get the +1 mag extension check that the mag catch is fully engaging with it installed. It's very common for it to only partly engage and then release under recoil. If this is the case you will need to sand the grip butt down a little until it fully catches.
Crimson Trace will be releasing a laser for it soon. It is much slimmer than the excellent ArmaLaser that is currently available. The Crimson Trace will also be activated by a pressure switch on the grip which unlike the ArmaLaser does not require your finger to be inside the trigger guard to have the laser activated.
