I did a few "poor man's trigger jobs" on a few less-expensive guns in years past when I didn't have any expendable income for such luxuries.
They all worked like a "poor man's trigger job".
In every instance, I just reinstalled the factory parts to restore factory reliability, or paid a real pro to do it correctly. There's a whole lot more to a top-notch trigger job than simply replacing a few springs, especially on mass-produced guns like these.
