Most gun bugs come and go for me, and that's how I know they're bugs. The ones that are persistent are the ones I consider real needs:
Latest bugs: bolt rifle in .338 WinMag, semi-auto 12ga, steel-framed pistol in 40S&W, 4" revolver in .357Mag, Glock 31 barrel
Real needs: pocket-carry .380 or 9mm, AR in .223/5.56 with an added 300 Blackout upper (ok, that last one is a bug)
