I thought that my first choice would be the NightGuard 325; .45 ACP, 6 rounds. But it is nearly the same weight as the Governor, and lists out at over $1,000.00. That makes for a pretty big spread in dollars. I would probably choose the Governor in light of the cost differential.
Note: The NightGuard comes with nicer sights, but does not accept any of the alternative ammunition. It is more compact than the Governor.
