A little giddy.. Just placed a pre order for the Hellcat OSP model and now just have to hurry up and wait. Brownells has a nice discount going on right now too with a code I saved just over $50 on it. Now the question is which optic to go with. Springfield is pushing the RMSc or whatever it is, not a fan. $400 and bad reviews from what I can tell. Just saw today the Sig Romo Zero which seems to be about the same size and should work for half the cost. I will have to wait and see till I get the gun if the Vortex or Trijicon RMR will fit. Anyone have any experience with any of those sights?
