This is a knock-off the Bubits armbrace that was originally designed for the Glock. I made this to fit the Sig P365 only. I threw some shapes together on TinkerCad.
It is held in place by friction and your grip. Prints in two pieces. I added a pic rail on the grip so that you can customize your choice of brace/stock.
