^ I have had the PX4 for about 4-5 years and I'd argue that it's a substantially better pistol than either the P95 or SD9VE. Good recommend for only $80 more.
I once would have said P95 to this. I love Ruger, and the P95 rocks. However, having played around with a SD9VE, it's a much nicer pistol than I expected for the money. Very cleanly machined.
