In SA mode, pull the trigger until it gets hard. Pulling it that far only takes about two pounds of pressure. That is where the struggle begins. The trigger creeps along as you apply increasing pressure, and finally breaks. When I first tested the gun, the average was 8 pounds, with some readings higher and a few lower. After some more firing, the average was closer to 7.5 pounds. I have seen worse, but this trigger really does suck.
In DA mode, the initial pull is considerably heavier than in SA, but once it tightens up it doesn't creep forever (as it does in SA), and it breaks at a little less weight than it does in SA. This pistol's terrible trigger was made even more evident when I fired a Glock 36 after I'd been using this gun. Although the Glock's trigger weighed in at roughly 7.75 pounds, it broke so quickly and smoothly that it felt excellent in comparison.
If you're a Glock shooter and you like to hold the trigger back after firing and use its short reset, you'll find the PT709's trigger familiar. Although the pull after reset weighs 8 pounds or more, it lacks the creep evident in its usual SA pull.
The photo above shows the right side of the PT709. Stamped into the slide we see TAURUS INT. MFG. above MIAMI, FL. - USA. Forward of the ejection port is PT709 above CAL. 9 mm. The serial number (also found in a metal tag in the frame) is engraved on the barrel and slide.
At the rear of the slide is the locking mechanism (which disables the gun), located just below the rear sight. You can use it or not, at your discretion. The two screws on the side of the plastic rear sight are for adjustment - the front one changes windage (clockwise to move it right), and the rear one adjusts elevation (clockwise to move it up).
