the issues the G17 can have... are the same issues the G18C can have... just the full auto fire increases the chances (and decreases the possible "time" till it happens)

the screw mount in the frame, the front of the slide... and I have seen reports of the full auto "sear" in the G18C failing ...

there is mention of how to reinforce the screw hole mount on the frame... a metal slide with a good recoil spring/buffer set up ... and shooters design has newer moar betterer full auto sears available.

I've got 1200-1300 rounds through mine .. in and out of a carbine as my primary outdoors

I have a "spare" complete lower (haven't gotten my complete top yet for twins) I'm gonna do the reinforcement to the screw mount... and switch over my existing slide assy, then I'll check/reinforce the screw mount on my original lower.

other then a couple small dimples in the top front corners of my slide from the Roni carbine kit ... I've had no damage or failures , however I have been gaming outdoors in pretty cool weather so the propane is not running full power.

^ please keep me up to date.
i saw a post of a hop-up failing, and can't seem to find a replacement. i would like to run on propane, eventually. but want to be sure i'm not shooting myself in the foot.

I havent had my TM G18C fail on me yet. The only thing that broke was the air nozzle which I have fixed and have replaced with a harder one.. Here are some upgrade parts that Im using for my G18C, but keep in mind, Im using most of these for short stroking with a functional mag catch. A;so, Im using a TK twist barrel (not shown below) and the slide/outer barrel set in the pic is by SD.

and your running propane?

yes

good to hear.
i've been concerned about running propane.
i'll run duster for a little while. i'm going to exopy the frame post to prevent cracking. maybe i'll run propane when i use the gun as a side arm, where i won't be using full auto, and duster when i'll be running full auto as my primary.

i always use propane to my TM G17 & KSC G18, dint know any thing else to use, lol!

anybody know where to get a injection valve for TM G17 and KSC G18 magazine? pm me pls!

Any problems with importing a Hera Arms glock kit? Anyone with any sucess?

Ive imported 2x. both were searched by CBSA, both passed without any problems!ive had my TM18c for about 4 weeks and 1000-1200 rounds on boht green and duster. Great gun!! accuracy measured at 150ft 100% hit on man sized target w/ .25g metal tech bbs. (on green).

my cousin has the same gun with the same upgrades - metal slide 150% recoil spring - after about 400-500 rounds his frame broke at the typical spot. after using JB-Weld to re glue it all back together, the gun works perfectly again!

im only taking a guess on this, so dont quote me.. but i usually do 3-5 round bursts on full auto. were as my cousin does full mag dumps. maybe the long busts freeze the lower frame making it more fragile??

Get an 18c! the way i thought if it is, its basically the same as a 17.. it just has an added benefit of full auto. for $10 difference, why not??

Or just get one from airsoftparts and avoid the hassle...

But yeah they get through fine, cause all it is is just a plastic rectangle.

I just picked up a marui g18, ran it with duster and it was horribly weak. Just pick up a metal slide and run propane through it..the kick on full auto with the metal slide is nothing short of amazing. People fear you hah
