I would suggest the *Fobus Evolution Paddle for your PPS. I have a similar holster that I carry my Glock Model 27 40 Cal. in. It is easy to put on and off and secures the pistol on my belt with good pistol retention. I have had it for probably 8 years and it works as well today as the day I purchased it.
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
-- John F. Kennedy
