Yeah, I'm thinking my next sidearm/backup is going to be a Marui Mk23 with STTI mags and all sorts of upgrades, namely a 14mm thread adapter, better silencer (KM, probably) and a nice tightbore. I'll have a go at making the LAM somewhat functional, if not just for the hell of having another project with an interesting outcome, since I'll probably never use it.
Super upgraded Marui G18c AEP with external battery lanyard. Nothing but pure sexiness. I'm also thinking about getting a TM Mk23 before they start going out of production or something crazy and I just end up wishing I had bought one...
