My friend at the LGS said this is an older model with a slide that is coated with nickel something. I have worked the slide and so forth, and everything seems to work okay. I was surprised to find that it has practically no sights at all. I don't intend to use this for SD. It is just a range toy and plinker. I won't have a chance to try it out until Wednesday. Since this is an older one, is there anything I should know about it? I don't know what changes they made to the newer ones. Do the newer magazines work better? Are they interchangeable with the older ones? Any knowledge would be appreciated. The members of this board have done a whole lot to better educate me. Please forgive the poor quality cell phone picture. In real life the dark parts look black.
