Notes: The EP-22, also known as the LA-22, is modeled on the P-08 Luger, but chambered for .22 Long Rifle ammunition. It was produced from 1964-1971, and is basically of a similar size and of comparable weight to the Luger. Some rare variants of the EP-22 include the Navy model, with a 5.9-inch barrel (as opposed to the 4.5-inch barrel of the standard EP-22), and a Carbine model with an 11.8-inch barrel, wooden fore-end, tangent-leaf rear sight, and a detachable stock.

The KGP-69 succeeded the EP-22 in production, and was manufactured until 1997. It adds a magazine safety and replaces the wooden grip plates with a molded plastic grip. However, the barrel is shorter at 3.9 inches. The KGP-68 is a version of the EP-22 firing either .32 ACP or .380 ACP ammunition, and having a shorter action and the same short barrel length as the KGP-69. The KGP-68A is a KGP-68 with a magazine safety, required by US laws at the time; Beeman also sold this pistol, calling it the MP-08.

Notes: Introduced in 1984, the EP-452 is externally modeled on the M-1911A1, though it is much smaller in size. Internally, the mechanism is quite different, as was necessary to use the .22 Long Rifle cartridge. The frame and slide are made of light alloy with a blackened finish, and the grips plates are of wood. The EP-457 is similar, but fires the .32 ACP round, has a faux stainless finish, and a slightly longer barrel. The EP-459 is similar to the EP-457, but fires .380 ACP.

Notes: Like many such Erma pistols, the EP-552 series was designed to resemble another pistol – in this case, the Walther PPK. It does resemble that weapon externally, though internally, it is quite different, and the slide and frame are made from light alloy. The EP-552 is the base weapon; it is quite small and light, and has a short barrel to match. The EP-555 is the same weapon, but fires .25 ACP ammunition. The EP-652 is a modernized EP-552; it has squared contours and does not resemble the PPK much any more. It is also lighter than the EP-552, due to a simplification of the pistol’s mechanism. The EP-655 is a .25 ACP version of the EP-652.

Notes: This is basically Erma’s version of the Walther P-38. This version is a compact pistol in .22 Long Rifle, with a safety catch that blocks both the bolt and the hammer, and a magazine catch on the heel of the butt. It is a simple, basic, small-caliber pistol. A variant, the EP-882S, has a 6-inch barrel, but is otherwise the same.
