I think mainly its a liability issue when it comes to adjustable triggers. some of remingtons adjust easily. Savage has both the adjustable and the accu-trigger. and a gunsmith can "clean up" the trigger on other rifles. remington has come out with their own version of the accu-trigger. I don't know anything about the mossberg 100 but seems I have heard some not so good things about them from those that have bought one, although you'll get differing opinions on just about any rifle. I was never interested in mossberg so I haven't payed much attention to the stories about them. After fit, the trigger is the biggest factor in shooting tight groups in my opinion. there is normally a disagreement amongst folks, but $$ is way down on my list of factors when it comes to purchasing anything. So i have to save longer or work extra to get the thing I want. In the long run I think I'm happier with the decision to go the extra.
