If your looking to replace that stock plastic trigger in your Para their are a few of the Kings aluminum NM triggers left on Ebay. These are for the double stack and I just picked one up for my P14. Supposedly minimal fitting is required. Very hard to find aftermarket triggers for the Para, the ones I did find were all out of stock.
