the second one looks like Walther P88...
Both these guns have a safety or hammer drop lever on the slide, the WALTHER P88 has nothing on the slide. If you look at the take down lever in photo 2 ,it looks like Beretta, so my guess it is a Beretta 92F with one of those closed top slides that I believe the navy had made up when the first production of the 92F slides started breaking.
