Personally i would prefer it if this mod launched the grapple hook from a crossbow. It looks out of place being fired from a pistol and doesnt sit correctly on it anyways. I use this mod for all the reusables it adds but i hidden the horrible grapple gun engram from the list on my server and installed a seperate reusable grapple hook mod that fires from crossbow. Rather i didnt feel the need to have a second mod just to make it look more natural.....

Beyond that though i do love the mod!
