You can get them for under $200, tax and all, to include a spare mag, in nice condition. They are an SA auto, like the 1911. 28 ozs, all machined steel, 7.2" long, 8 rd single stack mag. Nice sights, trigger pull, safety lever. Reliable, durable, fast handling,m accurate, nice wt for 9mm control. I'd sure buy two of them before I'd pay $400 for a used Glock 9mm.
Check for them at AimSurplus, J & G Sales, SOG Int'l, GunsAmerica.com, and GunBroker.com. They were the issue carry gun for the Spanish Federal cops for many years. The nicest ones have mostly all been sold, the ones seen now have quite a bit of holster wear, but almost all are still very sound, mechanically. There is one source of parts still available. With 2 of them, you can always practice with the "spare", and keep nearly all the wear and fouling off of the carry piece.
With the Corbon 100 gr PowRBall load, the 9mm is a pretty potent round, and it's quite controlable in this handy little gun.
