John,
I do believe that "explanation" has been thoroughly de-bunked
, it is for purposes of allowing crud (technical word) buildup to accumulate.
One member posted the original patent wording for this feature by Georg Luger and he states this as the purpose- no mention of gas venting.
If you look at the construction, this is true, the grooves don't extend far enough to vent any gas.
The Finns drilled a small hole in the bottom of the breech block for gas venting though.
