Ryan, welcome to the forum. The 40 is simply nasty (in a wonderful way)!
I've been using the Remington UMC in my 21. Nice and cheap, and even though Webphisher claims it's so dirty he gets a case of black-lung every time we go to the range, I like it, and it's plenty accurate. You might try a box to see if you like it (~$100 for 250 in 45 ACP).
Again, welcome and enjoy your new Glocks!
