I have a CZ 75 SAO and I primarily carry a full size Yost 1911 but I am thinking about adding a 9mm to round up but I live in CA so I cant just go out and buy a 9mm 1911 otherwise I would pick up a Wilson edcx9 or STi Staccato P. So I am thinking about sending off the CZ to CZ custom to have some work done as the SAO trigger is not the greatest and their new compact bull shadow setup looks really promising but I cant find much information the other question is to go RDS or not? I have never used an RDS on a pistol but it seems like thats the current trend is it worth milling a slide?
