Guarder Ridged Trigger for ISSC M22, SAI BLU, Lonewolf, & Compatible Airsoft Gas Blowback Pistols
(Color: Black)

"FIts perfectly on my old WE G17 gen3. The stock dingus doesn't lock the trigger anymore so this is a good replacement. Just remember where the slide stop/catch spring goes. It says for Marui G17/26 use only.

"Drop in fit for WE 18c gen 4 and KJW G23. Ordering another!

"Not quite a complete drop in. Installed in an APS stippled lower for my Marui G17. The trigger had to be filed a .100th of an inch as it was too tight in the frame with an APS extended slide release. It is a .100th thicker than the stock trigger which was JUST enough to cause the trigger to stick tremendously but after filing it works great!
