550 round reliability test.
« on: February 03, 2002, 03:15:08 PM »
I took my CZ 85 with Kadet out shooting yesterday and wanted to report my findings.  When I first installed my Kadet over a year ago,  I would get frequent stovepipes.  At lest 3 or 4 every 100 rounds or so.  Since this wasn't satisfactory to me I modified my ejector (see pub69.ezboard.com/fczechp...D=11.topic ) so that the brass ejected at a higher angle.   Yesterday I gave my conversion a thorough reliability test.  I fired a 550 round Federal Bulk pack of ammo though the gun just to see how reliable it is and because it's fun!!!  I had cleaned the kit completely the last time I shot it including the firing pin channel.  My second round was a light strike which fired on the second pull of the double action trigger.  I experience about 2 or 3 other light strikes in the 550 rounds fired.  None was ammo related as they all went bang on the second pull.  My only other malfunction was a low feed nose jam on the feedramp from a fresh mag.  This may have been my fault but regardless it's still not bad out of 550 rounds.  I fired the kit both slow fire and rapid fire, weak hand and strong hand as fast as I could pull the trigger and change mags  (3).   When you calculate averages I had  .5 % light strike and 0% failures to eject   .2% failure to feed which was probably my fault loading the mag or seating it in the grip.  Those of you who are experiencing a few stovepipes every 100 rounds or so might want to investigate the other posts.  What you will see is that there are two main reasons the Kadets malfunction.  The first is bad ejector angle.  The second is that some CZs are narrower than others which causes binding of the slide during the blowback cycle.  Once these two issues are addressed, you can expect outstanding reliability from your Kadet!  mapdude
