TM G26 acting up... Climate RELATED???

[MikeMcNair]

ok guys, by now you should know that i have built about 5 or so pretty sick guns on here, all glocks of some form.

issue i am having is virtually the same with BOTH guns i assembled last night:

fires one shot, fine.

fire next shot, pellet rolls out of barrel and all air is released.

now, one gun is heavily modded (see list below) the other is virtually stock, but BOTH are doing the EXACT same thing!!!!!

is this due to the VERY different ambient temps lately? (we went from 75-80 and sunny to high 40's at night in a day or so. it is currently in the low 50's.)

list of the stuff on the "uber glock" :

TM/KJW G26/27 hybrid

* Custom PDI 6.01 TBB
* GUARDER STEEL SLIDE AND BARREL (the holy grail!!!!)
* Guarder enhanced Recoil spring
* Guarder Enhanced Hammer spring
* Guarder Steel Recoil Guide Rod
* Guarder High Output Valve
* Guarder Steel Trigger Lever
* Guarder Steel Magazine Catch
* King Arms Air Seal Chamber
* Firefly Rocket Valve and Piston Head Set
* STEEL Magazine Extension
* STEEL Rear Sight
* KJW Heavy weight Frame
* SILVERBACk Laser sight
* Clipdraw Real Steel clip (replaces need for IWB Holster)
* BRAND NEW internals (every single part and spring)
* .30 BB Bastards or KSC Perfects (I have both in .30)

list of stuff on the "stockish" one:

TM G26
*GUARDER Mag Catch
*GUARDER high flow mag valve
*Metal Power up bulb in blow back unit
*6.03 TBB


thanks in advance for your help. you guys always come through for me!!

up top for help please

The higher temp might have blown one of the o rings inside the blow back unit out of place. The fact that your getting one proper shot off puzzles me.

[MikeMcNair]

yeah, and there are no o rings in the blowback unit, jut the loading nozzle, the valve, the spring, and the piston head

anyone else have any ideas?
