I have a ps90 on the way in! My first question is, there is a small sling slot I have seen in photos on the rear of the stock. Now, I already have a TROY single point sling. However, the straps at the end to mount to the gun are too short to go all the way around the entirety of the stock. It has two short straps and a "tri-loop" fastener as a gun mount. Will the small plastic slot support the weight of the gun on the sling without breaking?
