WA M92FS blowback device disassemble

[Gattorosso]

Hi,


Thank you for hosting me here. First let me apologize for my english but I am from Italy.

I have a WA M92FS and found that the o-ring on the blowback piston very often leave its seat and the pistol don’ t fire any more.

The solution looks to be to change the o-ring as it looks have been deformed and slips away from the seat too easily.

Here it is the trick; I disassembled the slide, the barrel, the back sight, the safety lever on the right but there is – apparently – no way to disassemble the one on the left and consequently the metal block located in the back of the slide, necessary to be withdrawn to access the blowback piston.

I looked for the pistol dwg and found it but all of the copies I saw show a screw in the back, item 95, that I cannot see in the pistol I have !

What do I miss ?

Thanks
