I had 2 Para Ordance POSs that had the LDA trigger. I love my P series Paras but the LDA trigger is ****. Both of the two that I owned a doublestack 45 and a single stack 9 had trigger issues. I had my local gunsmith fix both and sold them off.
I had a Eaa witness that kept breaking firing pins too but it was used and cheap so my expectations were low.
