Ha, join the club jurek! this is why I need these red dots.
I stand corrected Earl, the Phantom is in fact wider, I'm getting 1.07" on the Phantom, and .93" on the P-01 at the very back of the slides, the Phantom has what I think is "a lightening cut" that begins at the ejector cut on both sides of the slide all the way to the front sight, the P-01 doesn't do that. I'm thinking the RMR plate may overhang there, I'm hunting for photos. I really like the pistol but if I had to trade into a SP-01 or a Shadow to make it work I'd consider it. I'm still a CZ novice and learning as I go and the CZC Shadow has caught my attention for a full sized pistol. Knowing what I know now I think I'd strongly consider just purchasing the "worked over" pistols from CZC or CGW from the start, have them cut the slide, mount a plate where applicable and ship to my FFL.
Steve, very nice pistols!
