I dislike all of them. Guns suck.
I disliked the photos too ... but it wasn't because of the inanimate object in them.
As others have pointed out, the background was too busy ... yes, it may have been 'less bad' than a cluttered basement (or whatever), but less bad isn't really what one wants to strive for.
Similarly, as insurance / documentation illustrations, they should probably more follow a flat presentation (think 'Engineering Drawing'): skip the odd angles and partials. For small details such as your sights, close-ups are appropriate...some of these were mostly okay; I'd try to fill the frame more with them.
However, I wouldn't suggest having "insurance" illustrations that show the weapon with loaded clips (especially if it may be inferred that a loaded clip is in the weapon): this can raise uncertainty that you're not handling or storing the weapon safely.
Similarly, even though it breaks aesthetics, having the ejection port dust cover open and with a chamber flag insert will document safe handling practices. Sometimes there can be more read into an illustration than what's ever intended....such as that that box of 9mm was manufactured at East Alton, IL in December 2004.
Of course, if you're looking for more interesting illustrations, there's always stuff like purposefully induced failures:
