You can see how I lapped the slide to the frame. I am not peening the slide with the hammer, there is just enough material to cause friction. I put small amounts of diamond paste on the inside of the slide and remove very small amounts of that material using the force of a dead-blow hammer
Next is to adjust the barrel positioner with a file to get the outer barrel and barrel hood completely aligned with the lugs when the slide is at rest. Most Inokatsu slides sag in the rear of the slide, causing the slide to set itself ahead of the rear slide rails due to poor quality tolerances.
