Don't forget that thewide angle lens is distroting that picture and making it seem even wider.
One thing is that KSC glocks have no safety at all, the trigger is not supposed to flick up!!!
I should know, I have 7 of them.
If you want to get a nice finish on the chamber use Brasso to smooth it down, then use an alloy wheel/aluminum polish/stainless steel polish, that way you can get it to mirror shinyness!
Good start so far.
Meh the only KWA slide that I have ever broken was a METAL one. They are actually weaker as they are cast metal and don't take kindly to shocks or tensile loads.
IMHO the plastic slided G18c is better as it has a higher ROF.
