Materials & tools list
- generic tactical holster
- elastic straps (like these or maybe wider)
- thread & needle
- knife or scissors
How to make
Cut the holster's rear seam (see picture). Sew in elastic straps. They should be a little bit smaller then the width of the Hammershot to keep them on tension when the gun is in the holster. Just sew them in. Don't forget the bottom strap to prevent the gun from falling through the holster.
The straps may be made of Velcro® strips to have the holster adaptable to other blasters.
Also it may be possible to use only one broad elastic strap, such as the second leg lace, which I needed to remove.
