1. Ensure slide (everything to include extractor and extractor slot) are clean.
Gun very clean and polished
2. Replace extractor spring.
Tried extra power spring but did not work at all would not even chamber
2. Age and weight of recoil spring. May need to replace and may need to go 1-3 lbs lighter.
Springs no more than 1000 rounds, i put in brand new 10 pound
3. Face of ejector may need minor grinding to change ejection angle.
Have not done, would like to see a goo pic of this mod
4. Check extractor, breach face, & ejector for burrs. Don't polish but ensure they are smooth.
Polished
5. Can you video the pistol when firing (in slow motion) and see what is happening to the case that is stove piping?
Have not done this
6. Left side of the breach face (as you point the pistol) should have a curved area where the left side of the case is pushed by extractor pressure. There is a small groove facing to the right side of the pistol in the "ledge" Ensure it is clean and no powder residue buildup. Hope that is a good enough description to find what I am talking about.
Seems to be very clean and ok
---------. I did today try 135 power factor and ran great no issues. Im beginning to think the extra weight of the deltapoint pro is making 125 loads difficult to run. Maybe if i get slide milled maybe i can go little lighter load.......
