Folks,
I am still trying to understand different designs of self-loading systems used in guns.
Usual pistol/SMG/rifle descriptions say things like "locked-breech" or "roller-lock" or "rotating bolt".
Now, I do understand that such information can be seen as "dangerous" for propagation (as in "how-to-make-gun-at-home"), which would explain why there doesn't seem to be books or publications about this subject. The only one I've found so far is " Full Circle - A Treatise on Roller Locking" published by Collector Grade Publications:
