In addition to INGO, I hit czfirearms.us a bunch. They show 39K members, but who knows how many are active. Could be a lot since there seems to be a bunch of activity there. I also hit a couple of 1911 forums, like 1911addicts.com, M1911.org and 1911forum.com. That last one is very active with 5600 people online when I checked a moment ago and a stated 173k members. That would be a good one to advertise on because everyone knows that 1911 guys are nuts and throw money at anything with some 1s and a 9 in the name. I'll even bet some of those idiots spent more than $450 for a 1911.
