If you can’t identify the movie another way to do it might be to identify the base gun on which the prop is based then go to the internet movie firearms database
www.imfdb.org and trawl through all the entries were that particular gun appears.
For instance, that pistol has a grip shape and trigger-guard shape which looks to me like a Walther P99 and the grip shape and folding stock on the other prop looks to me like a Remington M31 RS2 riot shotgun.
