I think the whole promag 30 rd drum thing is something that promag had on their map but then dropped/delayed, because there are several sites that list them (allways out of stock/not available). simple math, promag makes hi-caps for the 995=1, promag makes polymer drums for other guns=1. so 1+1=?. Probably promag had/has the 30 rd drum in mind but possibly due to the disaster of their 15 rd mags for the 995 (all 3 of mine work in my 995), they either dropped or delayed it. If promag has/had interest/r&d time in a 30 rd drum but has for whatever reason not brought it to market, they won't be admitting it. That would be like KFC giving out it's 'original' recipe. either way don't hold your breath.
