Excellent guns. Accurate, fast, reduced "flip", ...and on and on. I cannot say enough about how impressed I am with these guns.
The trigger reset is a little different but once you figure it out it is outstanding. Field stripping is just different but once you learn the process it's just as fast as anything else (old models). Pull down on the front of the trigger guard and move to the side a little, pull slide to the rear and up. Done. Reassemble- point the slide down to the ground. put the square/flat side of the barrel against the top the slide and let it drop all the way through the front of the slide (like in recoil). Line up the guide rod and spring push the slide back to the read and down onto the frame. It's actually quick once you do it a few times.
New models have an updated disassembly button sort of like a glock.
Dropped factory night sights onto my P1 last night. A tremendous improvement.
