Analysis

Astra introduced the A-100 in 1990 as a simplified successor to the A-80 and A-90. The A-80 of 1982 had followed the SIG P220 in layout and controls but used a double-stack magazine; it was submitted for Spanish service trials and lost to the Llama M82. The A-90 of 1985 kept the decock lever and added a slide-mounted safety and a two-piece firing pin, which made the lockwork more complicated than the market wanted. The A-100 dropped that slide safety and relied on the decock lever, a firing-pin block, and a hammer safety. A 1993 running change raised magazine capacity. About 54,000 A-100s were built in 9 mm, .40 S&W, and .45 Auto before Astra wound the line down with the rest of the factory in the mid-1990s. The A-series saw some use with Lebanese Forces units, but it never won a major service contract. Used guns trade as inexpensive SIG-pattern steel pistols; parts and magazines are scarcer than for the Swiss guns they resemble.

My police Carry Gun for several years
By Nomad1820 on 10 May 2021
I carried an Astra A-100 as a duty and off duty weapon for the last several years of my Police Career. She served me well and was quit a comfortable carry weapon in my nylon duty gear. I easily qualified either 1st or 2nd for the department and our local SO as well as a neighboring Department who gathered with us on qualification day. The only officer who outshot me was the High Sheriff of our County, embarrassingly using an old S&W Military and Police that had long ago lost all it's bluing because of it's age. Of course the Sheriff had been in office for over 35 years and shot his old revolver at least once a week, just to keep in practice he used to say. I still have the pistol and even after years of sitting on my hip, providing me with protection that I could and did rely on, she looks almost new. That nylon doesn't wear on the muzzles like the old leather we used to wear for duty on the PD.
