Tonnes of stuff out there for the KSC G19:
Metal slides/barrels and recoil springs. PDI makes a piston head for KSC Glocks. There's a few hammer springs out there for KSC as well. There's also the "Rocket Valve" and Hi-Flow valves.
In short no shortage of aftermarket parts for KSC Glocks.
I would really like to do a side by side comparison of the TM and KSC Glocks but like I said I've never dealt with a TM Glock and only have experience with their M92F and Hi-Capa but from what I've seen if they carry over the quality of those pistols to their Glock line then they'll have no problems.
