The following weapons were used in Season 8 of the television series Archer:
Season 8 of Archer, now titled "Dreamland", takes place in 1947 in his head as he is in a coma. In this alternate universe, Archer is now a P.I. investigating the death of his partner (former servant) Woodhouse. All of the characters have new personalities and have been reintroduced to different roles, where Lana is now a singer at a bar, Pam is now a guy, and Malory, who goes by the name "Mother", is now the head of an mob organization that runs a jazz bar.
Archer's traditional and iconic Walther PPK has been switched to the American Colt M1911A1. Unlike previous seasons, Archer's M1911 is blued steel instead of satin nickel. Close up shots reveal that Archer's sidearm is also worn-out and has scratch markings on it, which could mean this is the same .45 he was issued when he was in the Army. Of note, the animators properly show the weapon as a single action handgun only, which means the hammer must be cocked for the weapon to fire.
Smith & Wesson Model 10
Sgt. Poovey and Det. Figgis' weapon of choice is a Smith & Wesson Model 10 revolver, specifically a "Military & Police" version, popular with Law Enforcement throughout the 20th Century.
Smith & Wesson Model 15
In "Berenice" (S8E2), Poovey's revolver he/she pulls out is a Smith & Wesson Model 15, unlike the M&P Model 10 in the previous episode; note the rear adjustable sights and pointed front post. This is the same revolver Det. Dietrich used last season as well, although it's appearance is slightly anachronistic as the Model 15 wasn't produced until 1949.
Luger P08
In "Ladyfingers" (S8E4), a German SS Officer confronts Dr. Krieger with a Luger P08 after finding out he was actually a university professor named Aaron Leibowitz, who was removed from his position for being Jewish.
Colt 1908 Vest Pocket
In "Waxing Gibbous" (S8E6),"Gramercy,Halberd" (S8E7) Lana can be seen using a Colt Model 1908 Vest Pocket semi-automatic handgun as her service weapon as she was revealed to be a "Treasury Agent"
Submachine Guns
M1928A1 Thompson
Several of Len Trexlor's gang members are seen using M1928A1 Thompson submachine guns, identifiable by the Cutts compensator, top mounted charging handle, flip-up adjustable rear sights, and finned barrel. It makes sense for these versions of the Thompson to be seen in mobsters hands, as the later M1 and M1A1 would most likely still be in military inventory.
MP40
German soldiers in a couple of flashbacks are seen equipped with MP40 submachine guns. This is the first time the MP40 is shown since Archer - Season 2. Since then, it was replaced by the more modern, but similarly German MP5.
Rifles
M1 Garand
In a brief-PTSD like flashback in Episode 1, Archer and a US soldier next to him are seen climbing down into troop transport carriers with M1 Garand rifles slung over their backs, possibly during Operation Overlord.
