Information

Pistol Information

An excellent article by Peter Kokalis on the wartime P.38 pistol can be found here, and another article on the post-war P38 here.

My post-war pistol has no date or date code - about when was it manufactured? You can get a rough estimate based upon these observed pistols.

Need to replace a broken WW2 slide part with a post-war part, and don't know if the new part will fit? Read the slide part compatibility guide. Note: this information is intended as a guide only. I am not a gunsmith. If you do not have working knowledge of the P.38 pistol, consult a competent gunsmith before attempting to effect repairs to your P.38.

Over the long term, will oil cause bakelite grips to deteriorate? An attempt to find out starts here. And continues after one year... and finally ends at three plus years.

Atarian's quick reference magazine guide. Helps to identify which magazine is correct for your pistol.

Atarian's post-war reproduction and aftermarket grip guide. Some of the currently available non-World War II grips for the P.38.

Can a "dipped" pistol be "un-dipped?" The answer is yes, and quite successfully. Take a look at zero series cyq serial number 030.

What's that 13 digit number on my pistol and/or magazine?

Information Exchange Pursuant to the OSCE Document on Small Arms and Light Weapons 2003, 2008, 2010. Note in 2002 the United States was by far the largest importer of German "Revolvers and Self-Loading Pistols" with 1,040,985 imported (of 1,082,797 - the balance of 41,812 or about 4% going to 20 other countries), while the Germans destroyed only 5,666 "surplus" pistols. In 2009 the US imported none and 17,520 surplus pistols were destroyed (none were exported to any country). See Annexes 2 and 3.

Frustrated, she minimized the PDF and looked at the raw collision data visualized on her main monitor. Each collision was a ghostly trace. Normal collisions looked like a simple 'V'—two paths in, two paths out. But her anomalous events looked like a tree branch: one path in, three paths out, but one of those outgoing paths looped backward in time on the graph.

Dr. Elara Vance had been staring at her screen for three hours. On it was a grainy scan of a classic textbook: Quantum Collision Theory by C.J. Joachain. The faded orange cover, the dense mathematical notation—it was her bible. But tonight, it was a cage. quantum collision theory joachain pdf

Elara slammed the emergency stop. The room went dark. When the backup lights hummed to life, her PDF was gone—replaced by a single blank page with a digital timestamp from tomorrow morning. Frustrated, she minimized the PDF and looked at

She maximized the Joachain PDF again and navigated not to the main text, but to the appendix. Appendix C: Time-Reversal Invariance in Scattering . She had always skipped the appendix. But tonight, she read the small, dense footnote: "It is generally assumed that the S-matrix is unitary. However, if the collision energy exceeds the threshold for pair production in a curved vacuum background, the unitarity cut develops a branch point that maps onto a closed timelike curve. The scattering amplitude then contains a term proportional to the future boundary condition." Elara froze. She had read this book a hundred times. She had never seen that footnote before. She scrolled back. The page number had changed. Appendix C now had a section D, which she knew for a fact did not exist in the original 1983 printing. But her anomalous events looked like a tree

She looked at Leo. "Joachain didn't write that footnote," she said quietly. "Someone else put it there. Someone who knew we would run this experiment today."
