Silver gun and heart necklace

Long delicate silver chain with a gun and heart pendants. The heart has a hole in it (by design). I found a 925 stamp on the heart only, maybe my eyes aren’t good enough to see it on the in and chain, but for sure silver since I am very allergic to metal and have not reacted to this necklace. It was also very tarnished and I cleaned with silver cleaner to get it in the condition it shows in. Total chain length is between 24 and 25 inches.
