Sig Sauer Auto Pistols Test Quiz Questions - P210/P220 Series

I am semi-retired and I am taking a self-passed and self-taught Armorers course on Sig Sauer Auto Pistols. I hope to become a part-time light Gunsmith in the future.

There are over 60 quiz questions covering this firearm and I have answered most of them. During my study and research I am having some problems related to some of the following quiz questions. Either I am not sure of the correct answer or I have conflicting answers.

Can you help me verify my answers or correct my answers for these few quiz questions?
