Verdict: Free in 4-1; do not upgrade it.
Take it for free in 4-1 (treasure chamber by the outside fountain, with Ashley) and don't upgrade it: 210,000pts to reach 28, and its exclusive doesn't show up until 5-3. Raise Capacity with an empty cylinder = free magnum rounds (the 12-round level opens in 5-1). A rocket (30,000pts) is cheaper for bosses.
