KSC G18C Part information

aZn_triXta07 · October 5th, 2006, 23:16

Hey everybody, I bought a used KSC G18C a while ago and I had a friend look over it yesterday. After he took it apart he found the only issue was that part # 267 is broken . I'd like to know would this be the ONLY cause to the slide not being able to recoil properly and releasing gas?

that is a major part to break it breaks easy and will stop the gun from working. from your pic's I see nothing else so I would say yes that part fixed and it should work.

From what I remember, the purpose of that part is to hold back the hammer (along with the other similar piece on the other side of the hammer), so that when the slide comes back after cocking it hits that little metal tab thing to the left of the hammer spring forward slightly, making the piece the trigger bar attaches to the only piece holding the hammer in place.

I see nothing else wrong visably, but you could have other pieces broken or not correctly placed with your blow back assembly. What kind of recoil issues are you having exactly?

aZn_triXta07 · October 6th, 2006, 02:23

What you said is excatly what is causing the slide being unable to cycle back and it causes the part that releases the gas to stay open and leak gas. This is what I've gathered so far from my friend. He told me that my hammer is a little higher up than usual while comparing with his KSC G18C. So yeah, there are no other broken pieces from what my friend has noticed, he can take more pictures if any of you are interested.

My main focus as of now is to be able to get my hands on part number 267, hopefully someone will be able to come through for me :S

On average, I have found if the gun has been used enough to have that part break; is the hammer itself can be worn enough on the notches on the it's side that the sear hold on to that the hammer is lifted up too far. The only way i have found to fix this is to buy a new hammer. I wanted to make this post just in case you did buy a new sear but found the hammer still sticks up too far. The only problem with this is that hammers are hard to get becuae they are common to wear/breaking and the only way to get parts for these guns is if a retailer goes out and strips down brand new guns for the parts. Hammers are useually the first peices to get sold.

Hmmm so you are saying that I should not only replace part# 267 but the actual hammer piece as well. I'll look it up in the gun diagram and look around :S. Like I said, if anyone knows anyone that could help me out ... please let me know :P

JohnnyDo · October 6th, 2006, 11:04

I'm saying that once you replace the broken full auto sear (part 267), and the hammer still sticks up too much and binds against the slide the next step is to look at the hammer.

aZn_triXta07 · October 6th, 2006, 11:30

Ahhhh okay, sorry bout that, I just thought I should get a replacement hammer as well (inexpensive) in case that situation comes up. Are there any other parts that you would recommend replacing just to be on the safe side?

JohnnyDo · October 7th, 2006, 01:22

- rocket valve .. get a firefly valve which is stainless steel I think, the stock ones are common to breaking
- both sears (part no . 267 and 266)
- hammer no. 263
- fireing pin no.78 and spring no.79 (or no.64 as they are the same)

those are the common things to go on guns in decent shape .. over time and use other parts will wear out or break but unless the g18 is your only gun and you use it every day .. the above parts are good to have on hand just in case for any glock owner.. that is if you can buy them.

aZn_triXta07 · October 13th, 2006, 10:56

Okay, I've ordered replacement parts directly from KSC, apparently they caught on to those parts breaking down so they are making higher quality ones now. All I'm looking for now is an upgraded firefly rocket valve (steel).

aZn_triXta07 · November 15th, 2006, 00:02

UPDATE: I've put in all my replacement parts, found out the hammer part I have is for a KSC G17 which explained the tightness. Now only problem is that when I fire the gun releases ALL the gas, and yes I replaced part no.267 which is making me believe it's something to do with the gas release. Anybody can help me out here?

manchovie · November 15th, 2006, 02:29

sounds like your rocket valve isnt moving freely.

aZn_triXta07 · November 15th, 2006, 23:06

Another update, I don't think it's the rocket valve, because I've taken this slide off and used it on my other fully working G18C base and it works fine. I compared the working hammer assembly with the broken one, and now I can get a few shots before the slide starts leaking, it's part 82 that's sticking out form what I gather. I also haven't really assembled my trigger, where part no.92 connects to the trigger correctly so it doesn't sound normal. Errr ... any suggestions?
