For all versions with asymetrical front of magazine shaft and only two fixing holes.
For a left handed grip you need a
left handed version of the AW93!
If you want to mount a left handed grip to a right handed AW93, you have to drill the fixing holes with a 3.5 mm drill bit on the other side of the frame and cut a 4mm thread.
If your AW93 has a serial no. more than 3400, you have to choose
this version!
