Pricing an 'abundant ammunition' magic item?

[Mr. Shiny]

I don't have a lot of experience pricing homebrew magic items, so I figured I'd toss this one out to the experts on the boards.

Gunslinger is looking to get a magic item crafted that would magically generate his ammunition (replicating the Abundant Ammunition spell)

spell is a 1st-level wiz/sor, and would only require a caster level 1; this means it's 1(spell level)x 1(caster level) x 2000gp so far.

If it's not assigned to a specific body slot, it's doubled.

4,000 gp seems a little low. Am I missing something?

PS- At 10th level, is it reasonable to give him this type of item so we no longer have to keep track of the 6gp per shot? We don't normally track ammo usage, but we've never had a gunslinger use costly ammo before either.

Here you should find some help.

I read it as 1(SpL) x1(CL) x2000(continuous) x2(1min/lvl duration) x2(slotless)
for 8000gp

I'd probably treat it as a +1 enhancement to the weapon and call it a day. With 2k gold, he could buy 333 shots, which is a high enough number to be infinite for most gaming purposes, so why not price an infinite number of shots similarly.

[MacGurcules]

Yeah, 8000 gp is right for continuous, unless it took up the belt slot or something.

The cost effective, if somewhat less efficient, method would be to make a command word item to cast Abundant Ammunition, but you'd have to use a standard action at the beginning of every combat and it'd only last ten rounds.

Spell level 1 x Caster level 1 x 1800 gp x 2 for slotless = 3600gp

That's enough to pay for 600 paper cartridges. Doesn't seem too low to me.

My GM made me pay 3000 gp. Reckoning a "Permanecy"ed 1st level spell would cost 2500 gp + casting of "Permanency" ist seems a fair price.

Btw: It's not just paper cartridges that you can take from the pouch. Any non-magical bullet taken out will be replaced. So I made sure to put some silver bullets and pitted bullets into the pouch as well.
