The most famous weapon to come out of the series, or possibly any series, is the "UNCLE Special" issued to agents Napoleon Solo (Robert Vaughn) and Illya Kuryakin (David McCallum). With an attachable stock, scope, and barrel extension, the pistol quickly turns into a carbine. The producers were looking for a versatile and distinctive weapon to have on their show, one that could be adapted as the plot required.
1934 Mauser Pocket Pistol
The first attempt at the UNCLE Special was based on a 1934 Mauser Pocket Pistol. It was introduced in the second episode, as the pilot had Solo carrying a Luger P08. The Mauser variant only lasted one episode however, as the pistol was too small for all of the attachments, it did not photograph well, and even worse, didn't handle blanks well. There were continuity errors throughout the second episode, as Solo switched to a Walther P38 whenever he had to fire his weapon.

Walther P38
As the Mauser had been unable to cycle blanks, the armorers had to borrow Walther P38s from the nearby Combat! set. A bigger pistol firing reliable 9mm blanks, the P38 was a logical replacement for the smaller, .32 caliber Mauser. Eventually, six UNCLE guns were produced at the cost of $1500 apiece, although only two of them were full upgraded, with should stock, scope, barrel extension, and even full auto. While the modifications rendered the guns incapable of firing real rounds, the full auto modification caught the attention of the Treasury department, which fined the studio $2000.
