Ok, finally got my extra long pin and installed it couple of days ago. Along with that I did put an extra longer set screw for the main spring and after all this it ignites everything that I throw in it. Double, single action, rapid fire. Blazers 38 special, federal, Winchester etc etc
It's super reliable now and OMG it's so accurate
Here is the target at 25 meters, 8 shots of 357 mag with the red dot
