I feel the best .25 ACP in my collection is the Astra 2000, all steel, forged frame, much better sights than many like the BB for instance, and a huge plus, exposed hammer.
I refuse all white metal framed guns, which includes "alloy" (aluminum alloy).
Zinc alloy framed guns were designed for limited use, if you've ever tried to repair a Zamak part you know what I'm talking about.
Zinc guns> GSO, or "Gun shaped object".
I have many much more expensive .25's but none better utility than the Astra Cubs.
