P46 gun

p46 gun may refer to:

• Twin bees shuttle-based p46 glider guns

• Bi-gun (early 1970s)
• New gun 1 and its variants (1971)
• Paul Callahan's p46 edge shooter (1994)
• Vacuum (1997)

• Period-46 glider guns in general

• The current smallest p46 glider gun, using the traffic stop catalyst (2021)
• iNoMed's other gun with a novel engine, that (when capped) is the Tamale (2022)
• Heinrich Koenig's Tanner's p46-only gun, the first without a twin bees shuttle (2017)

• Other Tanner's p46-based guns

• Glider gun built by David Bell (2017)
• p46 gliderless LWSS gun (2018)
• p46 gliderless MWSS gun (2017)

Note also that, using only twin bees shuttles, p46 guns for the LWSS, MWSS and HWSS (not involving the formation of intermediate gliders) were already known since the 1990's, due to the MWSS out of the blue reaction.
