You'll find divided opinions on Glock triggers. Many will say it's fine as is, others modify theirs or replace the trigger assembly altogether. I agree with you about the long, gritty, heavy, etc. I have a Gen 4 19 that was this way. I came from years of shooting tuned 1911's and the Glock trigger was like an attack from an alien planet. I tried the .25 trigger job, new connector and it didn't do much good. Trigger pull on my scale was just under 7lb. I was shooting IDPA with it and picked up a Gen 3 34 for a match gun. Trigger pull was lighter at just over 4.5lb but I still didn't like the long takeup. There's a lot of replacement triggers out there. ZEV, Glocktriggers.com, Johnny Glock, DK Custom, and a couple of others. I replaced the entire trigger assembly with one from DK Custom and couldn't be happier. The long takeup is gone, and the hammer drops at 3lb even on the 34. Liked it so well I replaced the one in the 19 as well, except I swapped the 4lb striker spring with the 4.5lb that comes in the kit. The 19 now pulls at 3.5lb even.
