Well as the others I have a P01 and a P10c and a p07. They are great guns in fact I don't know which I like better. Every time I put one in my hand I like it.
Anyway, yes the texture is a bit aggressive, but I handled that in about 3 minutes, I took some medium sandpaper and folded it down 4 times so it was stiff and sanded a bit then felt it until I got it where I wanted it bingo fast and perfect.
Yes the mag release was stiff but after using it it has eased up, no big deal. I worked it some while sitting around.
The gun is super in most every way, it feels tight and of good quality, the trigger is really good, about 5 to 5 1/2lbs. now short reset and audible, very quick follow up shots.
Sights are good, It's more accurate than me, plus for me my P07 mags also fit it. It is a superior gun to the Glocks I used to have. The only negative I see is if you are a person that needs a lot of mags, these are a bit pricy now, maybe they will get cheaper as time goes by.
I thought I might wait to purchase it, to save a little money but realized it will take a long time for it to get cheaper the way they are selling, so I jumped in and I'm glad I did it.
