Own a 995 in an ATI stock. It's fun and cheap to shoot. (Even cheaper than my AK.) It's my home defense gun right now, as I'm waiting on my pistol permit, and 9mm will probably kill less of my neighbors than 7.62x39 or 7.62x54R if I miss. (Houses on either side of mine about 50 feet away. I'm not confident that 9mm will stop at my walls, but I'm SURE that any 30 caliber rounds will not.)
The 15 round mags are a mixed bag. Some people have good luck with them, some people cannot get them to function at all. Some people have modded the feed lips, or the spring, or the follower and gotten them to work, some people have used them as target practice.
I hear the newest 15 round magazines have been improved and now seem to function better, but I haven't gotten to try any of them as I live in Screw York. :banghead:
