Torchwood agents Gwen Cooper (Eve Myles), Dr. Owen Harper (Burn Gorman), Ianto Jones (Gareth David-Lloyd) and Toshiko Sato (Naoko Mori) continue to carry the Tokyo Marui Hi-Capa 4.3. In "Adam", the alien infiltrator using the alias Adam Smith (Bryan Dick) is also seen carrying one after inserting himself into the Torchwood team. In "A Day in the Death", head bodyguard Farrington (Louis Decosta Johnson) carries one as his personal weapon. In a flashback to 1999 in "Fragments", the former Torchwood Three leader Alex Hopkins (Julian Lewis Jones) appears to use a Hi-Capa also. The weapon is further used in "Exit Wounds" by Gray (Lachlan Nieboer), Jack's brother.
In "Meat", Dr. Owen Harper (Burn Gorman) disarms one of the criminals of a Beretta 92FS. Another is later used by Dave (Marek Oravec) in the same episode.
In "Meat", a Glock 17 is carried Dale (Matt Ryan). In "Reset", security guards at The Pharm also carry the Glock 17 as their standard issue sidearm, with some seemingly adapted to fire tranquiliser darts.
An alien Blowfish (Paul Kasey) uses a stainless FN Model 1910 to take a family hostage in the Kiss Kiss, Bang Bang. He is killed by the recently returned Captain Jack Harkness (John Barrowman) before he can use it.
One of the firearms that Captain John Hart (James Marsters) hands over to Torchwood in "Kiss Kiss, Bang Bang" is a nickel plated Remington 1866 Derringer with pearl grips.
In "Meat", Greg (Gerard Carey) is seen carrying a Heckler & Koch USP as his main weapon. In "Reset", a USP is wielded by Professor Aaron Copley (Alan Dale).
Captain Jack Harkness (John Barrowman) continues to carry a a Webley Mk IV in .38 as his primary weapon. Captain John Hart (James Marsters) briefly uses it in "Kiss Kiss, Bang Bang".
Another weapon briefly seen in the Torchwood Three armory is a Dalek-modified variant of the M1921 Thompson, last seen in the Doctor Who Season 3 episode "Evolution of the Daleks".
A pair of H&K MP5K-PDWs are used by Captain John Hart (James Marsters) during the Season 2 finale Exit Wounds. The folding stocks have been removed, however the PDW backplate is still present, as noted by the hinge that the stocks would normally attach to. Also present are the lugged barrels of the PDW variant, onto which the standard H&K flash-hiders have been attached.
In "Sleeper", a British Army soldier is seem armed with a Heckler & Koch G36K. Although this is not accurate to real life (as the British Army uses the L85), it is consistent with the continuity of the parent show. Several G36KV's are also seen in the armoury of Torchwood Three throughout the series.
British Army soldiers guarding the nuclear stockpile in "Sleeper" are armed with Mk 18 Mod 0 carbines fitted with EOtech sights, foregrips, and tactical flashlights. The leader alien sleeper agent (Doug Rollins) briefly uses one to kill some of the soldiers.
In "Meat", Captain Jack Harkness (John Barrowman), Dr. Owen Harper (Burn Gorman), Gwen Cooper (Eve Myles) and Ianto Jones (Gareth David-Lloyd carry custom stun pistols as a non-lethal option. They have the Torchwood logo marked on the side.
Several Energy Blasters are seen in Torchwood Three's armory throughout the series. They were previously used by Rose Tyler (Billie Piper) in the Doctor Who Season 4 episode "The Stolen Earth", and before then by The Preachers in Doctor Who Season 2.
