Something you may want to consider here. If the trigger isnt horrible (I know, that can be subjective), Id just leave it be and shoot it. What happens is, the gun will smooth out over time as it wears in, and youre muscle tone will increase and things will seem to lighten up even more as you gain tone.
I shoot all my DA revolvers and autos, DAO, and havent thumb cocked any of them in years. I shoot factory stock triggers, and have no issues doing so, and have only found a couple, out of a boatload of guns, that were what Id call "bad".
But then again, Im used to shooting that way, all the time, and my muscles are up to it. When I first learned to shoot that way, that wasnt always the case, and it felt like the trigger was horribly heavy. Now, unless of course something is very wrong, which is also very rare, the DA triggers feel fine, and I dont pay attention to them when I shoot anyway. I focus on the sights and shoot.
Im not saying some things cant benefit from a trigger job, but I just think a lot of that is unnecessary and more of a crutch than a help. Doing trigger jobs on everythng, just makes you need a trigger job on everything.
Learn to shoot them as they come, and have the muscle tone there, and you can pick up pretty much anything you might come across and shoot them well, and without bother.
At least thats how its been for me. In the close to 60 years Ive been shooting now, Ive only had a couple of guns that were bad enough I had to have a trigger job on, and one other old CZ70 that I didnt bother. That one had a DA trigger that took two finger to pull.
