Once AGC started doing it, yeah, I started shooting 3gun. I try to make it a point not to dump money into guns without using them hard first to understand what problems they have... the M3K is a great gun out of the box, but like every other shotgun, the port needed much more aggressive opening for quads. I figured if I was going to send it out for that, I may as well go all the way. The slug rear sight is kind of a nice to have since MEGARMS keeps friggin' putting slugs into the stages.I love my M3000. I have a bunch of MOA mods but I didn't do all the three-gun stuff since there's nowhere to do that down here. Do you?
I like it on my competition gun, but I would have mixed feelings about it on a defensive shotgun. If you don't load aggressively, you can wind up with the LL dropping a shell on the lifter but not quite getting the shell all the way into battery - I think the mag tube spring has to be compressed a bit to build up a little velocity (these LLs really require a strong mag spring). The likelihood that you're gonna be loading twins/quads in a defensive situation is nil, and a port load is thus not going to be as big a speed hit.I may add the lightning lifter to my regular gun though.
