Cooper has written very little I disagree with. As I recall he was pretty consistently disparaging of DA triggers on autos, complaining that the CZ75 was encumbered with the "crunchenticker."
I'd venture to guess that his comment referenced above was probably tempered with something like, "If you have only shot revolvers your entire life, and have a pathological fear of cocked and locked carry, and need your Mommy to load your gun for you, the Seecamp conversion is the best of both worlds. A long DA pull for you milksops who think anything less than a 12 pound pull is horrendously unsafe, coupled with the One True Trigger for when you finally overcome your atavistic fears, take your thumb out of your mouth, and use it to deactivate the safety."
That's how I like to imagine he felt, anyway.
