This is a loop design for my WE glock 19, but should be compatible with most other glock models. 

I made it as a remix of my own base backplate , but this time with a loop attached.
This was a idea i came up with in order to not have zip ties on either the trigger guard or the grip as it is in the way and i find it irritating.

The gap on the underside might need a little widening as the tolerance can be a bit tight, this can easily be done by heating it up with ie. a lighter or heatgun, and then using a screwdriver to widen it
