I am helping a friend find a used 1911 and I need a few questions answered. I found a 1911A1 series 80 stainless gun that has been fired less than 100 rounds. It is the older model with the LARGE roll mark on the slide. I have read that this model has a plastic trigger. Are there other plastic parts in this gun? Are there any good reasons to stay away from this gun? My buddy had a budget of $600 and this one will just fit that budget. He can get it for $560.00 plus shipping. Is that a fair,good,great or bad deal? Thanks!!
