Interestingly, Japanese navy’s document says different data.

Collection of National Archives of Japan
Tateyama Naval Gunnery School, "[Military Secret] [Reference for Ground Battles Part 1] Specification Sheets of the Ground Weapons"
JP: 館山海軍砲術学校研究部「[軍極秘] [陸戦兵器参考 第一号] 陸戦兵器要目表」
https://www.digital.archives.go.jp/img.pdf/1724884
This document was captured in Okinawa at June 26, 1945.

According to this sheet, both naval SMGs have different specification.

  • Type Be (SIG M1920): fire rate is 1,100 rounds per minute
  • Type Su (S1-100): fire rate is 750 rounds per minute and magazine is 30 rounds

I am not sure which is correct and should be careful. To be honesty, I doubt SIG M1920’s fire rate reaches 1,100 rpm.

In addition, this document have two naval weapons suitable for assaulters.
Type 100 SMG special model is a naval variant of Type 100 for paratroopers. They modified this gun to foldable type.
Type 4 double-barrel shotgun pistol is a naval unique double-barrel pistol with 12 gauge shotgun ammo.
