I've been chasing my tail for a while with my 38 super Caspian thinking over pressure was causing chop but that's not the issue. One of my friends has fired my rounds with his STI and they look completely normal confirming it is indeed something with my pistol.
To give you a run down of how it first started I was having issues with primer chop jamming up the firing pin with slivers of primer, refer to the picture of three casings and notice the chopped primers on them.
Reading an EGW article on firing pins about primer flow/chop I discovered that early Caspian's used an odd sized pin, so upon measurement of the firing pin and comparing it to the frames hole, it was under sized by .011" and discovered that i have an early slide. I ordered a new pin and headed to the range. So that fixed the heavy chopping of the primer face issue.
But I'm still getting quite a bit of primer flow into the pin channel and a tiny tiny amount of chop. Check out the second pictures.
Reading some articles some say the chamfer on the breach face could be too heavy and its giving the primer an area to funnel into, well my breach face has a chamfer but not deep enough to be the issue as its barely even a noticeable chamfer.
Also I've stumbled across some posts elsewhere that talk about having too light of an ignition train. Well I am running a titanium strut and titanium mainspring cap top with a 17# main spring, could this be the issue?
Hopefully some one on here has dealt with this issue, and has some pointers.... please!!!!!
