I have one. Its a decent trigger. The bump fire part of it is nothing to write home about. It WILL do the bump fire thing, but its much more difficult to do it with the Tac Con than a slide fire. I am not particularly impressed with it overall, and for the money they are asking for them you can get a nice Geiselle (sp) or a Timney or one of many others that will give you a better trigger, and still have enough for a slide fire is that is what you are after. It's neat to have the 3 position safety and all, but not at the price tag it comes with.
