My little contribution:
It was a stock TM P226 until recently, its now been upgraded with:
Metal kit
Metal outer barrel (non threaded)
Stronger recoil spring (but left the original hammer spring in-place)
Enhanced nozzle
Enhanced piston lid
All parts are from Guarder. Also, I'm curious to know what peoples unique ID numbers are on their Guarder kit's. Mine is IS U001 54*
Cheers
