Some questions about finned & saboted projectiles in small arms...

[cdhknives]

I hear tell a 410 shotshell, properly prepared by emptying the shot, can be combined with certain arrows to make a heck of a finned dart...scale down as necessary for handguns. The length of projectile required for stability is going to be a problem...best research stability rules for arrows and similar nonrotated projectiles.

Tranq darts are another similar use.
