While I agree w/your comments on the safety of a “cocked and locked” .45 ACP, the accuracy of the above quote regarding the Glock safety system depends on how you define “functionally,”
If you mean that both double action revolvers and Glocks will discharge if you pull the trigger w/sufficient force; I agree; however, the Glock Gen 4 pistols have a 3-part safety system;
3. Firing Pin Block
See page 9 of the below linked .pdf file for a diagram of the Glock Safety System:
I am not aware of any revolvers that have the same type of three-part, redundant safety system as the Glock.
Two comments: While the trigger pull force might be the same on the Glock and revolvers, 10 lbs or so, the length of the trigger pull is much longer on most DA revolvers than the Glock. This makes the DA revolver somewhat “safer” IMHO.
Ruger (and I think Taurus) have transfer bar safeties which prevent the revolver from firing unless the trigger is completely depressed. I believe this provides the same resistance to drops or partial trigger pulls as does the Glock.
This was not a dump on Glock. I own and use one. I know about their internal mechanics. I was simply addressing the issue of “one in the chamber, or not”.
