P-01 all the way. The first mag I shot I pulled the target back and thought " Holy crap I have never shot a group that tight in my life." I then wanted to see how reliable it was so I fired, over a 3 week period, 960 rounds, 64 mags without ANY cleaning of WWB with no malfunctions of any kind. In 5 years and almost 6,000 rounds I had one round that didn't fully go into battery, WWB, that is IT!
It truly is in a class by itself.
