That is basically what I said.
After they had called in our ID's and everything came back , they continued to detain us and the officers slowly walked around all of us, checking that state of our weapons. When officer "Abuser" saw that I had my hammer back and unlocked, he questioned me as to why I had it like that and I explained to him that in the training I have been in up to now has proven that memory movements and unlocking your handgun can cause unwanted delay in reaction and I wanted to be in the "ready state" if I needed to use it.
He then continued to grill me with questions, like "what training?" and "who was your trainer?" and some other questions I don't recall exactly, but then he asked me if there was one in the chamber and I said "yes, don't you have one in yours?"
He then commanded me to de-cock and remove my magazine and I refused saying "No, sir...I will not"
That's when he reached for his cuffs and I pretty much knew where it was going from there. I proceeded to ask, "what law have I violated?" and it was not answered but I was told I was being cuffed for officer's safety.
Actually, there's an odd consistency. In the same way OCing is somehow more dangerous to officer safety than CCing, carrying an exposed hammer weapon cocked is more dangerous than a cocked weapon with a hidden hammer.
It makes perfect sense in the weird twisted logic that made him think it was okay to handcuff a citizen for absolutely nothing.
