Interesting one this, we have a WE double barreled 1911 which is a *tad* (awesomely) overpriced at £140 seen as they retail at £170ish, especially considering the shitty condition.
The real eye opener for me is the G18c, which is described as the usual 'pretty much as new' despite having a fucked front end from being yeeted during a game. So, second hand, skirmished and damaged we're asking £4 more than you can presently buy a G18c brand new from Firesupport. The reasoning on this one is the addition of a Serpa holster, which from quick general reading is also second hand and hot garbage anyway.
Oh, and that's plus postage which I guarantee won't be cheaper than Firesupports postage, widening the gap further.
This thing of lumping unwanted accessories in with a gun that isn't worth the asking in the first place needs to go away and die. That and the nearly/as/pretty much new thing. It's either new or it's second hand. If you've removed it from the package, taken it to a game and run it, it's definitely second hand. 'New' should not appear anywhere in the description, ESPECIALLY if you've tried to use it as a lawn dart. 🙄
