One of the major efficiency gainers, IMO, is the detent. It reduces front bolt friction and gives extra shots. The one I have does not have the tippmann detent slot in it, it's good to know this will work with it there, thanks!
I found taking the point of the triggerguard and rounding it off helps holstering.
