I have a P9 Ultra IPSC.
Great gun. Great trigger. I have had it since the middle 90's and while I have worn the original barrel badly (trying to turn a 40 into a 10) it is still a fun gun to shoot. I have over 10,000 rounds down mine with no significant problems after the first month. I broke a slide stop back in 95 but it was replaced under warantee.
I would go with the P9 given the option.
