One of the local shops has an all black Springfield base model 1911. Thier asking $510 (used) for the gun and offered me a pretty good trade for my Glock 23. Im mainly wondering if there are any specific factory options that I sould check for that would hurt reliability or performance if absent. I can live with no rail, I just want it to function well. It did appear to have pretty nice sights on it. The gun seems to be in pretty good condition.
