A competent Armorer would assure correct function and loading.
I agree. The blue haired girl did not seem to be competent. I have also read that the gun has been used for 40 years in various movies.

In that time with all the (mis)handling, it is possible that someone could have modified it so it could drop the hammer without the trigger being pulled.

It is a movie gun so at some point the hammer notches may have filed down, the sear modified or removed or the trigger pinned back to make fanning it easier.

Dipshit said he pulled the hammer back a bit, then more, then more. Then the gun fired. Entirely possible with a modified gun if his thumb slipped off the hammer.
