DB, I'm not advocating this, merely asking the question in reference to the P320 and similar pistols that are making inroads in the duty pistol market. Decocking or carrying on-safe aren't options for these users.
This conundrum popped into my head comparing the Walther P99 with the PPQ. In another thread a poster mentioned they'll never carry the P99 because they can't decock it one handed. If, in a situation where two handed decocking isn't possible, why not revert to PPQ mode and simply holster the gun (is the second hand were injured or otherwise tied up and couldn't be used to decock).
A big reason why my agency went to Gen4 G17s was that it was very difficult to train recruits to properly operate the P226. The whole "stop, decock, and holster" took too much training time.
