A working man with a pistol - imagine that Welcome aboard!
Myself I love my 3rd gen Glock 23 but did not like the finger spacers. I sent it in to Bowie Tactical Concepts and am having them removed, as well as a few other mods like reducing the grip for my fat hands. I don't think it was so much the finger grips that were a problem but the size of the grip. That's why I'm having it reduced.
From that other forum Glock Talk
"Both are Glock. The Gen2 runs fine, just as the Gen3 does. I have both and consider them equal. I prefer the Gen2 for CCW and the Gen3 for home with a light.
Main changes, aside from the most obvious finger grooves and rail, include the extra pin for the block (and change to block itself; meaning they are NOT interchangeable) and the "1" stamped barrel (slight ramp change and bevel at top of barrel hood). Slide finish is more matte on the Gen2 also."
Have you tried on a set of G19 3rd gen pistols yet? Try it you may like it.
