Suppressors Lipsey's Rugged Obsidian45 or Lipsey's Gemtech Lunar-45 Suppressor

My local gun shop has become a Class III dealer and I want another suppressor. On paper, both the Rugged Obsidian45 and Gemtech Lunar-45 meet my basic requirements for a pistol suppressor to be used with .45ACP and 9mm.
Does anyone have first-hand experience with either of these suppressors and, if so, what are your thoughts?

Thank you, Richard
