There seems to be a few solutions to adding a K-grip to receiver of a M11/9. In my view, the OEM hanging strap is just plain unsafe. Below is brief review of what is available to M11 owners. Please give your feedback if you own one of these products. If there are other methods I missed, please let us know.
Methods
1) Add a picatinny rail to the underside requiring drilling into receiver.
2) Use the M11 barrel as an attachment point.
3) Use the threaded barrel as a support for a barrel extension with grip
4) use the M11 frame and receiver pin.
Example Products
1) SCA Armory Special ops Tactical front grip
2) FTF Industries screw on K-grip
3) Practical Solutions M11 Flip Grip
4) Surefirearms M-11 Folding, Forward Steel Grip
5) Stony Creek M11 Tri-Rail W/ grip,3 long rails, sling swivel
