A period-53 glider gun is any glider gun with period 53. The first true period glider gun was discovered by iNoMed on January 22, 2024 based on a partial by goldenratio from December 2021. It is the only known period-53 glider gun. It was originally stabilized with two p53 pi-heptomino hasslers, but it had been found that it can be stabilized with one sparker only, while the transparent block can be restored using an eater 1 and a Gourmet catalyst.
