Great bright fiber but poa/poi problem - TruGlo Brite-Site TFX Pro Sight Set For CZ 75 Series

According to TruGlo's website, this model should fit all CZ 75 series pistols, including the P-01, which is the gun I ordered these for. After an easy install (they fit my P-01 slide perfectly), I was impressed with both the very bright fiber tubes in daylight and the better than average tritium brightness at night. So far, I was very happy with these sights. The problem started when I shot with these for the first time at the range. I set the target at 12 Yards and my impacts from benchrest using a combat hold were consistently 4 to 6 inches low. I tried another ammunition type, same result. Upon doing further web research and taking measurements of factory sights vs TruGlo sights, it seems that the front sight height is designed for the full-size CZ 75 pistols and is too high for the compact P-01, resulting in low impacts. While TruGlo's statement that these fit the P-01 is technically correct in that the footprint fits the front and rear slide cuts, they neglected to indicate that the front sight height is only accurate when used on the full-size series of CZ 75 pistols. I will be either returning to factory sights or ordering a lower front sight from Dawson Precision. So, I'm out the purchase money and will throw these in the parts box in case I ever purchase a full-size CZ 75 in the future. So, I would definitely recommend these sights if you have a full-size CZ 75, but DO NOT BUY if you have a P-01.
