Thinking on your comment just a bit more, GJM...
In one training scenario I did a few times, the P229 was field stripped and dumped in a bucket...the magazine was taken apart and dumped in same bucket...12 rounds of Gold Dot in the bucket.
You then commenced with 50 knees, alternating a knee, on a heavy body bag, then max pushups for 2 minutes. Upon completion of this exertion, you put the magazine components together, put the rounds in the magazine, put your gun back together...load and engage three racks of steel, various large and small targets...under time...and against another peer.
Out of 40 students, even the bad shooters, I did not see a single light 4 - 4.5 SA pull go off prematurely on a steel plate, between a transition, at charging the hastily assembled handgun or in an emergency reload.
Hearts were racing.
This is not to invalidate your comment, just sharing an experience that has bearing on your comment.
Food for thought is all.
