No, it does not... because you can press the trigger with the bolt out of battery and have it travel under spring pressure forward towards the firing pin, but if the bolt is not in battery, the hammer cannot strike the firing pin. The bolt can be out of battery by an inch and allow the hammer to fall. If your guy had his bolt that far out of battery  where the hammer cannot be released, which is what I believe your explaining, then he has bigger issues. How can some one have there gun in that kind of condition and be ready to engage targets???  Sounds more like a training issue. So he transitions... unless hes engaging hordes of bad guys and this sounds like a training scenario, then he finishes the drill with a pistol...accesses,  reloads and holsters, and then gets his primary up...

Apparently he never looks  in his ejection port or uses the dust cover... amazing how that little piece can keep out foreign debris. and if you take a quick look and then close it between firing, it eliminates a lot of "Million to one" malfunctions.

Your right, sounds like a million to one, You have your SOP's.. I have mine...
