Lesson to those of us who are a novice CZ owner. If you want to fully upgrade your CZ decocker pistol, and are not familiar with the decocker mechanism, don't do what I did. Just send it to Cajun Gun Works in the beginning. I bought the 97 BD for $675 and figured I could spend $300 to buy CGW parts to upgrade the pistol.
After losing springs, damaging a few pins, having to enlist a local gunsmith to correct an installation error, and on, and on, and on, I have invested $1,592.32. If I would have bought one already decked out from CGW I would have spent about a $100 less and had zero aggravation. Oh well, at least it has given me something to do in the days of my retirement.
