Yeah I do believe a WE G18 would be the best for skirmishing however, I've already had that feeling and now I want to try out other type of guns. I haven't gone skirmishing yet and I want to get a feel of it at home first so I thought shell ejecting would be cool lol.
I've had a look at Hi Capa and they look amazing. As for the 1911 shell ejecting I;ve seen a video on it on YouTube but I can't find an actual link for it on google to purchase one unfortunately.
