XDM is my choice. You can get a 4.1 oz tungsten guide rod to keep it down and you can get mag extensions so you can start 21+1. I dont like the magwell options since they all have to use a med backstrap, but in limited you just need 1 reload on a long stage anyway.
On empty gun table starts the grip sits up about 6 inches and its like grabbing it from a holster.
