Congrats on your ProC. This is my daily carry with Federal 147/Hydra-Shok JHP's. Range ammo for me is normally Winchester (white box) 115/FMJ or Magtech 115/FMC (available locally at a reasonable price). Good to hear you had a pleasing day at the range. This pistol is a real treat, especially for the price. If the sights were comfortable to you already, you're in for a lot of enjoyable shooting.
FYI/FWIW and mentioned in other threads, I really like the Bianchi CarryLok #82 cut for the Glock 19. High, tight, secure, easy break-in period, and ultimately comfortable while enduring a lot of windshield time. Will handle the 24/7, so you have a little barrel space left over with your Compact, but everything fits like a glove and the lock works extremely well, even with my little paw.
As for the mag spacers, good luck. It's a crap shoot getting them with the 17rd mags from Taurus and they've NEVER shown up from aftermarket sources (from Taurus). Just a matter of time I suspect.
