reaper has a set of 8 or 10 western minis
Yeah, look at Reaper's Chronoscope line as well as their pirate figures.
Depending on what you're looking for, a lot of Privateer Press stuff may be suitable as well.
If you want more specific suggestions, please let us know race and other important details (fantasy, steampunk, what kind of armor are they wearing, do they use other weapons, etc. etc. etc. ).
:) actually I was being too snarky for my own good.
I'm basically asking for Paizo to have WizKids make some gunslinger minis for Pathfinder.
Currently have started Skull & Shackles, and we have a human female gunslinger...
Does anyone know of any plans to add these to a set in the future?
Well, we're only getting minis of what they have art for, unless they have art for more gunslingers, we won't see them as minis. Maybe more art came in the NPC Codex? If not I can't see it happening
The sculptors need an image to work from. Part of the license is that the minis need to feel like they are part of the world (see the complaints about the orcs and lizardmen in H&M). As of right now, there are 2 gunslingers that have art I can think of. The Iconic, and the one from Ed Greenwood's web fiction.
Privateer Press would seem like the best choice. Depending on what exactly you want, they've probably got something that will work. And they're very nice figures.
Some of the old WOTC Star Wars prepainted plastic minis would also be suitable substitutes for gunslingers.
For other alternative sources for prepainted gunslinger minis, I believe that there were prepainted plastic minis for the some of the Arkham Horror board games/the Adventurers board games (in a special standalone set) by FFG.
Another FFG board game, Tannhauser, also uses prepainted plastic minis.
