Ive owned both, shot both, and still own the Taurus PT809. I had a small gun channel and did a full A-Z review on it that got a bunch of positive feedback from other owners. The 800 series is really impressive and completely revolutionary for Taurus. They MIGHT just make a new name for themselves in the semi market with that series.
Anyways, all things considered I Think the Taurus PT809 is way ahead of the P95. I grew to really dislike my P95 after a while.....its bulky, hated the trigger, hated the appearance, and it lost its finish way sooner than any other gun I owned.
My favorite things about the PT809 are the look, the feel, the weight, the accuracy...and most importantly the trigger. Its got a VERY impressive DA/SA trigger and the SA trigger break and reset is up there next to Sig and S&W. Incredible trigger. Anyways I just posted on a similar thread about a budget semi for the price of $380 you can get this gun which serves as a nice back-up/night stand type gun. A little big for carry in my opinion because it has a very large grip (although they do make a compact model) but a very versatile gun.
Also, I just ran a 2k round challenge through this gun to really put it to the test. I fired 2k rounds straight over the course of 3 months with no cleaning/lube and it did great. Only 3 malfunctions and 2 of them were due to the mag. The mags for this gun are OK but certainly not great.....I think the follower got hung up a couple times due to carbon/grit build up which I blame for 2 failures to feed during the 2k challenge. Still, this gun is batting 99% in my opinion and I love it! EXTREMELY light recoil and accurate as hell
