Glock 18C Repair

Not sure if this is the place to post it in...

But...

I was wondering if anyone knew were, or how to repair a KSC Glock 18C.

I was playing at these hills at the end of 152nd st, and I was using my friend's crappy holster and well, my gun fell...

And it wouldn't have been so bad, except for the fact that the week before something fell out of the rear end of the slide, and I'm pretty sure it's a part that holds the selector switch in place.(I still have that part) But, the selector switch and the ball bearing fell out; and in that place there was no chance in hell of finding it.

I ordered the selector switch and the ball bearing, and am going to pick it up Monday; but I have no idea on how I'm supposed to put that part that fell out back in...

If anyone would be willing to help me, I'd be willing to pay for the service.

If you ordered the part from one of the local shops, then take the whole gun with you when you pick up the piece and they will probably install it for you for free. Just ask them if they know how to put it back together. Good luck.

They don't sell any Glock parts in america other than mags and pointless upgrades.

I ordered it from www.Tokyo-Model.com.hk. By the way, it's the best site for upgrades and parts, and pistols. But it takes a while, because it's in Hong Kong.

I missed the delivery and I have to pick it up from the post office tomorrow.
