The bit about slide lock back giving an indication of empty vs a revolver blows my mind. Here's a visual aid for why. "S" is semi, "R" is revolver. The numbers below are round count.

S. R.
1. 1.
2. 2.
3. 3.
4. 4.
5. 5.
6. 6.
7. Empty, "benefiting" from no slide lock.
8.
9.
10.
11.
12.
13.
14.
15.

While you're hoping that lack of slide lock is going to somehow convince a bad guy that you still have rounds, despite the fact that you just inexplicably stopped dumping rounds (likely clicking 1-2 dry cylinders, since nobody actually counts rounds in a gunfight), the other guy is still shooting.

Call me crazy, but when I hit 6 or 7, I'd rather keep firing than hope the BG is fooled.
