At one of my mosly club matches, Dave Olhasso, former Beretta Factory Team IPSC Shooter who had recently switched to a Springfield XD, asked to handle my Matt/Angus built SPO1 recntly, turns out Angus is building him one for the World Shoot.
Then yesterday I went to the Max Michel/Travis Thomasie Double Impact course (2nd time I have taken it, great guys, great instruction, tons of trigger time), Max who shoots Open, is also getting a gun ready for either the Nats this month or the World Shoot, also has a brand new SP01 in his holster.
He didnt have the 85 trigger like mine do, tried mine, and said I have to get this trigger in my CZ. He did comment that his gun needed to feel/function more like mine before, he would be totally comfortable with it at a major match.
