Not as I recall, but I cannot swear I am right. The stuff to which I referred was 40-odd years ago, and what brain space I have has been consumed by other details. I will admit that I did approach the issue and respond from inside my own experiences and biases, which are almost entirely related to defensive use of firearms. Included in those would be a preference for a smooth trigger (face), and a reasonably smooth trigger press.
