I've owned six Para double stacks and all have ran well out of the box. The one issue I did have was a barrel chambered slightly off center with the bore. One phone call and a replacement was in the mail that day. I thought it was refreshing to deal with a tech that knew what he was doing and a big plus not haveing to ship the whole gun for a replacement part. He did quiz me to see if I knew how to fit a barrel if needed.
I used to have one and the only reason I sold it is because $$ got tight. Never had any problems with it. It functioned well and shot very accurately. Great pistol!
