If there was standardization, you could use anybody's MIG gun on your machine. As it is now, you're very limited. When I got my machine, I assumed I could put any gun on there I wanted; boy was I wrong. It just so happens that Lincoln makes a gun to fit a Miller machine using a Miller connector installed on the Lincoln gun. They must've worked out some kind of business arrangement I assume. I'm glad they did.
The Miller MDX100 that comes with the machine has a ridge on the handle ( shown by the red arrow ) in an effort to form a finger groove. I frickin hate it. It doesn't allow me to place my hand where I want it and gets in my way. Enter the Lincoln 175L MIG gun. That thing is a life saver. The handle is bigger, has a nice smooth trigger without serrations, and the neck is bent at more of an angle. I dodged a huge bullet thanks to Lincoln. But I wish I could use a MIG gun from any manufacturer.
