tm m92fs biohazard.
10+ cans of green gas with no problems
less than 1 can on propain and the rear sight broke off including the rear top of the slide

ksc usp compact
1 can coleman propane
as well as darklen the safety dose not work still decocks but no safety.

KSC G23F

3 cans of green gas so far.

Small tearing away of slide catch, but functions perfectly.

Nothing too interesting in the history, I take good care of it.

I'll keep running it on propane until it breaks, and then buy all the upgrades my little heart desires...

ksc glock 23f. on the second mag through this brand new gun, blew the slide clean off. (propane). selector switch is loose after that also.

Yes, my friend has the same problem. It seems to only happen for him when the mag is emptied, leading me to believe it has something to do with the chipped away slide catch.

looking good! thanks for the input. I'm hoping to get perhaps over 15 reports on each of the common models to get a good statistical representation of typical useage. I may have to group common models (e.g. WA 0.45 series GBBs) to get a useful number of occurances to draw conclusions.

Gun: WA SVI 5" Limited
PRIME metal slide
Guarder springs, hammer and nozzle

History and failures:
Came to me extremely well used, I believe with 134a. The only problem was a worn feed ramp on the loading nozzle, and I replaced the nozzle, as well as the slide and springs.
After approximately one to two cans of propane, the hammer started to develop cracks. It was disintegrated after another can of propane, and was replaced with Guarder's steel hammer. It's probably into it's fifth or sixth can of propane by now, still with no serious problems that weren't caused by me. The blowback chamber is usually loose after a game, even if I loctite the screws, which is a little odd.

GBB model: KSC Glock 19 w/ Metal Slide and outer barrel. Highflow valves on mags. Upgraded recoil rod and spring.

Quantity and type of propellent used to date: 20+ cans green gas

Failures to date: none

Interesting history: Dropped once or twice during cqb. No longer own this GBB, but it was a workhorse.

GBB model: TM mk23 nbb (I'm the second owner)

propellent: I've put through at least 2 cans of propane, got the gun used and it was always on propane. probalby another couple cans there.

Failures to date: none at all (gun wise). no signs of wear or problems other then the common mk23 mag presure valve went after the 2nd can of gas (by me). used 5 minute epoxy on and around the main seals and valve. gun is still working 100%

Generally for CQB i've been useing this gun as my main gun. I go through a good 5 - 10 mags of ammo in a game night. good point about propane is because the gun is so efficient with it's gas I can use 3 mags of of ammo with one fill up with propane.

GBB: KSC Glock 19 with metal slide
Propellent: at least 6 bottles of Propane
Use: For over a year, thousands and thousands of rounds fired.
Mods: Upgraded spring.

Notes: Pretty hard on my guns, been bumped, dropped, and cleaned infrequently. The only thing I do religiously is put a lot of oil in the top of the propane bottle when I am filling my mags. Have 5 mags that don't leak at all.

IMO: If you are looking for a reliable gun, I don't know of a better one.

GBB model:WE-TECH hicapa(second owner)

Propellent:1 bottle of coleman propane

Failure:Twisted loading nozzle, probably happens when using Tm mags doesn't cycle with TM mags anymore but works flawlesly with original mag.

model - TM 5.1" hicapa
propellent - ~2 CT propane bottles
use - ~3-4 months
mods - halfway through its life, upgraded return spring, shooters design slide, barrel, chamber cover, pdi piston head, freedom art railed frame/steel hammer pin (5.1"), wider valve in the breech machined by a friend
stock slide seemed to have minimal wear and tear at time of replacement
issues - the thumb safety acts a little funky, the right thumb saftety becomes slightly detatched after shooting ~4 mags or when left by itself for a few days; probably because i didnt put it back together properly; fixed by just pushing it back in

WA 1934 Beretta
HFC134
Been droped a few times
No issues what so ever

Marushin Browning 1910 (NBB)
Greengas, propaine, HFC134
No issues what so ever

KJW M9 Beretta
Green gas only
No issues What so Ever

WA 1911A1
HFC134
Cracked slide, needs new recoil spring, new hammer

Marushin Derringer
HFC134
Leaks of and on but I have never had any big issues.

Is it the one I bought? I was going to post it hehe.

KWA Glock 19 FMU w/ upgraded recoil spring.
7x bottles of coleman propane
1xGreen gas (1000ml)

Out of 6 mags, only one leaked.

Gun is still in great shape, No problems.

KSC USP Compact with upgraded recoil spring, hammer spring, metal outer barrel, metal slide.

3x bottles of propane have been used (fired about 5000 shots)

Problem #1: Hopup rubber broke in its first few weeks after its purchase.

Problem #2: Three days ago, a week after installing the hammer spring, the trigger snapped.

Problem #3: When firing the slide sometimes gets stuck on the hopup rubber, causing it to embed itself into it. Which means during some games the slide has to be moved into the proper position after every shot.

Problem #4: The safety switch no longer functions. Noticed this after a month of use.

In my opinion, installing a hammer spring was a very bad idea. It puts way too much stress on the trigger which is made of very poor metal.

I take good care of my pistol, i clean it and lube it after every use. has been dropped a few times and left in the dirt. But I don't scratch my guns i love them too much.

All of my magazines work flawlessly but a broken trigger means a useless pistol now untill a replacement trigger can be found :(
