I was just wandering if anyone had tried out the P250 yet, looks like an interesting concept & I thought I might "stimulate" the economy with the purchase of one. Does anyone know if the slides and grips are interchangeable, could you mate a full size frame assy. w/sub-compact grip? What size grip , sm, med, or lg is the gun shipped with and how can you tell the difference? Has anyone installed the short trigger in their P250 yet? Thanks all.
