Luger Heavy Barrel Not Cycling

[Blastattack]

Here are my wrench plans:

The wrench head is made from 4140 Cold Rolled rectangular bar, 1" x 4". The handle is made of 4140 Heat Treated & Stress Relieved (HTSR, also Quenched and Tempered), received in Turned, Ground and Polished condition, and is 13" x 1.000" diameter. The handle has a 1" long by .751" diameter section on one end and is pressed into the body of the wrench. I also drilled and tapped a 1/4-20 hold and further secured the handle with a bolt.
