The german anti-tank gun 5 cm PaK 38 was better than this american weapon.Even so, number of this gun were bigger than 5 cm PaK 38 , in levels of production.Agre22 (talk) 22:55, 20 September 2008 (UTC)agre22
Well, the M3 was good design that fitted the requirements. The infantry branch wanted a gun of roughly the same size and weight as Pak 35/36 and that was what they got; the performance of the M3 was probably slightly better than that of Pak 36 (it's tricky to compare penetration figures, but the M3 fired somewhat heavier projectile with somewhat higher muzzle velocity). Quite possibly the M3 was the best of the "37 mm generation", the only problem was that it took the US Army too much time to fully recognize the need for something more powerful (and by necessity heavier... e.g. the Pak 38 was about twice as heavy, Pak 40 about four times, etc)...

so would it be monstrous of me to finish adding all the versions of this. since surfing around I dont find the complete list anywhere? Brian in denver (talk) 16:08, 11 May 2009 (UTC)
It's only my opinion, but I don't think they should be here. The idea was to list all guns related to the M3 (common development history, same ammunition, ...), not all 37 mm guns in US service. M1916 and AA/aircraft autocannons are completely different beasts. Bukvoed (talk) 14:40, 12 May 2009 (UTC)
Moved unrelated models to a separate paragraph. Bukvoed (talk) 06:20, 2 September 2009 (UTC)
