hey folks I just purchased a tact 45 and have the Combat/Competit LEM trigger on it, which is very smooth. However I can't shoot that well with the adjustable sights that come on this thing. Yes, I do plan to replace them with the Meps (orange in the back and green in front), however has anyone had trouble shooting with these manafacter sights they put on the Tact 45(the high adjustables?) Maybe I'm just used to the Meps? I do ok at 10/15 yards or less, but at 20 or 25 I'm not terrible but way worse than with my glock and I can't live with that. Time for Meps, just haven't had the cash. Thanks for any input.
