There was a thread on Hornady Critical Defense ammo about a year ago.  Several forum members had failure-to-go-bang issues with certain lots of Hornady C.D.  
 
For what it's worth, I think the biggest attraction of Hornady C.D. is its (relatively) reasonable price compared to other brands of premium ammo.  BUT, unlike the other brands of premium ammo - Hornady does NOT make its own primers*, thus they can't control primer quality.  Because other members have had issues, I would not carry my R9 with C.D. ammo.  
*Remember, there was a really severe primer shortage in 2009 - 2010.  For a period of 6 months I could not buy a single primer from anyone!  Finally bought 1000 Fiocchi small pistol primers.  Imagine what its like for a volume manufacturer who needs to buy in quantities of 100,000 or 200,000 per week!
