Dwight, I would be more willing to accept your "logic" on this subject, if you had actually run some test and had some experimental data to report. I agree that venting excess gas thru a hole in the bottom of the breech block is probably an improvement in a M23 DWM, but this was only done because a PROBLEM EXISTED. I believe that Mauser's use a the vented firing pin, was probably equally effective. TH
