I just had my new sights installed (see above photo). At 7 yards, my groupings are typically within a 2"-3" radius of center with a few outliers, but with the new sights my center shifted downward by 1"-1-1/2", which is a little disappointing. I wonder if this is something peculiar to the older TFX [update: no, it isn't], and whether the newer TFX Pro's are more accurate [update: no, not according to Truglo]. But I just replaced my grips to Hogues, too, and they are not perfect to my natural grip, so that could be causing it, too. I'm not going to get dismayed yet. I've only been to the range once since putting on new sights and grips, and have a few things to try out to try to identify what is affecting my shooting. @Jigo: I'm glad to hear the TFX Pro's worked out really well on your CZ compacts -- and a good tip, too, thanks. I shoot the #3 sight picture, too, which makes it surprising why I'm shooting a little low since changing everything out.
