If anyone has some insight of the innerworkings of the Suomi drum and could clearify some of my questions I would be thankful. You may have seen my 40 cal extended mag in my previous post... I'm planning on doing something simular with the drum mag. On simple observation, it does not look like it would be much of a problem. First question would it be worth the effort and cost? I may end up going through 2 to 3 of these 20-30 dollar mags before getting it right. Second, How baddly would this throw off the firing characteristics of the 995 ? Seems like it would be back heavy. Third, would all the rounds feed or stop at the top of the drum? Lastly, would this be a complete terd or a head turner ? Anyother technical advise would be appriciated as well, thanks.
