I'd like to compare experiences/discoveries with other Taurus PT709/740 owners/shooters/smiths.
My 709 started exhibiting erratic trigger force and by that I mean the required trigger pull would vary anywhere between 3 lb and 10 lb. I understand that this is no target pistol but I found that wide variation disconcerting; I was particularly concerned about the very light force measurements. I have read of others with heavy triggers (like 9 lb) who sent their gun back to Taurus for repair and were generally happy with the result although the repair tickets were pretty vague about what was replaced/adjusted/repaired. My problem seems different to the extent the force varies shot-to-shot. Given that the problem is intermittent I cannot be sure exactly when it began.
As an aside, Taurus previously replaced the front sight and the barrel (and maybe other things) because the pistol shot low and I replaced the extractor which cured an incomplete extraction/jamming problem. Other than this trigger force issue, the pistol is now reliable so I'm reluctant to send it back to Taurus again.
Prior to this problem I had removed the firing pin (striker) assembly a few times for cleaning, etc. and I think this may be related. The owners manual advises not to disassemble the slide (which would include removing the striker). The striker/firing pin rides inside a plastic sleeve and that sleeve controls the vertical position of the firing pin lug with respect to the frame and the sear. The plastic sleeve also rubs against the Taurus Locking mechanism when removing the firing pin assembly and it takes a bit of force to push the firing pin assembly out of the slide.
So I think it's possible that this plastic sleeve was deformed in a way that causes the firing pin lug to press down against the sear causing the high forces. Also, sometimes the sear fails to catch the firing pin lug if the slide is racked very briskly (this has never happened with ammo loaded). I suspect the plastic sleeve may cause the firing pin lug to be too low causing it to strike the sear prematurely, sometimes causing it to bounce and not fully engage the lug (sometimes missing it entirely) or to catch the lug squarely but also press down with excessive force making sear release difficult
I have read in many places that the 709 is supposed to have a great trigger so I think my gun has a problem. I would be interested in feedback from others who have experienced and (especially) solved 709 trigger issues.
By the way, I previously asked about this on the Taurus Armed site but the responses were along the lines of "that's normal for a belly gun" or "send it to Taurus". I don't agree with the first solution and I don't want to return the gun for such an intermittent problem.
Thanks in advance for any insights.
