Some gun things. The good cop talks to Reacher about his BUG and says it is a 32 Cal snubby. It looks like a SW but can't be sure. Since it isn't a blued gun, I'm not sure of the model as I don't recall a hammered SS or lighweight modern 32. Could be a Taurus, I supposed.
Shot out two tires with 4 shots from the 32. Doable? I did once see a 45 ACP bounce off a tire and come back and hit a guy in the chest, just a bruise though.
The bad FBI guy is holding Reacher at gun point with a 380 something, Sig? I can see that he doesn't want to use his duty gun but a 380 on a giant guy?
The knife does look like my Kershaw, the opening does look assisted rather than automatic. But who knows.
