I have the 24/7 Pro in .45 and It has (had) the Heinie 2 dot sights. Hate them. I shot low as well. There are a LOT of talk about shooing low at the Taurus Forums
Just take a look around in there at the 24/7 category and you'll find them. They shoot different. Rather than at six-o'clock position, they are designed to have the front sight dot "cover" the target. I'm not used to that, so redesigned my rear sight with some epoxy, and then cut new slot in the epoxy with my file. Colored it black with magic marker, and then put in 2 small indents on either side and used luminous pain for them and the front sight. Works like a charm now.
The 24/7 shoots SA on the first round chambered. So the trigger pull is not heavy but rather light, around 3 1/2 lbs. MUCH lighter than a 1911 I have shot in previous years. It is the Heinie sight, not the trigger. Mine is crisp and a real shooter. I had a Glock once in .40 Short & Weak and this is so much better pistol than the Glock not even close. Let the target tell the tale.
5 shot group at 15 yards. ALMOST had a 10 on the one on the left. All the other 4 are grouped together.
