Hi guys, came back from the range today. Was a good and a bad day there. A friend of mine came along and also took his CZ75 along. The same one I have bought at the same gunsmith. Both are the older version (not B). I have been wondering howcome my shots all come in to low. Well I found out today in direct comparisson whith my friends CZ75. The front sight on my pistol filed down a bit. Enough that the LPA rear sight I had monted didn`t match up and also enough that I have to aim very high to get the round into the center of the target. Has anaybody here changed the front sight on a CZ75 not B version?
