As I remember, a barrel is cosidered a firearm
allegra is right shihan.
As per EO 197 Dated June 6, 2000, Article 1-G states "Any extra slide/barrel or conversion kit shall be assessed a corresponding license fee amount to fifty percent (50%) of the rate for the said caliber".
If you your concern is the legality of you actions, then have it license. If not, then it's your call on bring the .40 cal. conversion kit everytime you go to any comp.;Q
