Sterling Archer's primary sidearm is a Walther PPK. The rendering of the PPK improves as the show goes on, but it's very primitive during the first season. According to the companion book How to Archer: The Ultimate Guide to Espionage and Style and Women and Also Cocktails Ever Written, his PPK is chambered in .32 ACP.
Captain Lammers uses a Beretta 92F in "Skytanic." Archer also uses a suppressed Beretta 92F in one scene in "Skorpio." Lana Kane also carries a pair of Beretta 92F pistols in a dual-pistol shoulder rig.
Since retiring from the field, Malory Archer's primary handgun is a Smith & Wesson Model 629, tricked out with a scope and laser. She sleeps with it by her beside in "Dial M for Mother."
Archer's rival, Barry Dillon, carries a nickel Desert Eagle Mark VII which he talks TO, not WITH. Lana Kane also uses a nickel Desert Eagle on occasion.
A SIG-Sauer P226 is seen on the floor in "Skorpio." It is missing most of its controls.

This is a real movie gun and has appeared in several motion pictures.Error creating thumbnail: File missingOne of Skorpio's henchman reaches for the P226 before Archer puts a bullet through his head.
Unidentified pistol
Major Jakov's assistant uses an unknown pistol in "Dial M for Mother" (S01E10).
Lana Kane is often seen with a pair of TEC-9's, which would be a good fit for her Johnny Bench-ian, steam-shovelly, Truckasaurus hands. According to the dialogue, they are TEC-9s, and fire full auto, but lack the sling rings of a TEC-9.
Cyril channels Private Pyle from Full Metal Jacket with an M14 after Lana decides to sleep with all the men at ISIS as a form of revenge in "Dial M for Mother."
An M21 rifle is seen in a crate during a flashback to the last moments of Agents Ruiz, Pak, and Mgumbe (all of which recycle the same background) in "Diversity Hire."
Skorpio's henchmen prepare to fire rocket launchers at Archer and Lana in "Skorpio." These are probably supposed to be FIM-43 Redeye missiles, since Skorpio was supposed to be selling them, but don't look like Redeyes at all.
This is the pistol that Archer gives to Cyril in "Training Day." The name comes from the literary technique "Chekhov's gun," which comes into play later in this episode. It's never seen again after "Training Day." They can never seem to nail down a design. According to the companion book How to Archer: The Ultimate Guide to Espionage and Style and Women and Also Cocktails Ever Written, it's supposed to be a Walther TPH.
Scaling, as seen in the armory shots above, used to be a problem, especially in the early episodes.
Error creating thumbnail: File missingArcher looks at the equipment that Krieger issued for Cyril in the second episode, "Training Day." There's what appears to be an out of scale SIG-Sauer P220, which, compared to the poison pen, (and the cap which slips off for like, no reason), might be only four inches long.Error creating thumbnail: File missingA closer shot. It is properly scaled by episode 4.
The PPK
Consistency was also not a strongpoint in Season 1.
