Glock .45 ACP 4256 Trigger Bar Evolution

[acss502]

I recently bought a Glock 30S from a fellow INGO'er and started looking into a trigger assembly. I polished my own on my G19 Trigger bar and was planning on doing the same for the 30S. When I stripped the gun, I immediately noticed the 4256-2 stamped on the trigger bar. After some research, I found that there are 4 (?) iterations of the .45 ACP trigger. With this being my first .45 Glock, I was wondering if anyone had experience with the different trigger bars. I've heard some are lighter or smoother then others. Any info or knowledge is appreciated. Thanks!

I have an older Glock 30 with a 4256 trigger bar. It seems pretty smooth, maybe lighter, but I have run quite a few rounds through it. Thought about putting a 3.5lb connector in it, but it could be a waste of $20.
