Don't know if this is the proper place to ask this but if not I guess I'll be told.
I'm trading off my CS40 but decided to remove the Big Dog grips and put the OEM ones back on. The deal isn't good enough to throw those in. Anyway, what would be a fair price to ask for them? Might just put them on my CS9 or CS45.
I know they aren't made anymore.
Keeping up with forum posts and queries about them, it appears that there is continual interest in them. I paid about $100 for mine several years ago when BigDog was still making them. Might be a reasonable asking price.
