With Love Gun, KISS eased up slightly on the hard rock sound that was so prominently featured on their previous two releases, Destroyer and Rock and Roll Over. Songs like "Christine Sixteen" and "Plaster Caster" were slightly more pop-oriented than past efforts, though songs such as Love Gun, Almost Human, and the fast driving I Stole Your Love, showed they still retained their hard rock edge.

Love Gun is notable for being the first KISS album to feature a lead vocal performance from lead guitarist Ace Frehley. Frehley had written or co-written several songs many fans consider classics — "Cold Gin" and "Parasite", for example, both of which are sung by Gene Simmons, and Strange Ways, sung by Peter Criss. But Frehley had never sung lead up until the recording of "Shock Me", which was inspired by a real life event. On December 11, 1976, KISS was playing at the Lakeland Civic Center in Lakeland, Florida. It was the first show on the Rock and Roll Over tour. Frehley began descending the stairs on one side of the stage. The railing wasn't grounded and Frehley was nearly electrocuted. Although he suffered burns on his hand, Frehley was able to continue after a short delay to receive medical attention. He later claimed he had no feeling in his hand.

The legend is that Ace Frehley was forced to record the lead vocal track by Simmons and Paul Stanley, but a self-conscious Frehley insisted on singing while lying on his back and out of view. Some fans dispute this due to the fact that for years, Frehley had sung backing vocals live with no hint of trepidation. However, the legend may also have roots in fact. For the Rock and Roll Over album, Frehley had written a song called "Queen for a Day" that did not make the final cut. [1] Thus, it can be argued that when Frehley or any of his bandmates speak of him recording his first lead vocal, they're confusing "Shock Me" with "Queen for a Day".

The song "Plaster Caster" was inspired by Cynthia Plaster Caster, a former groupie who is infamous for casting penises of famous rock musicians like Jimi Hendrix and Frank Zappa, as well as breasts of female music artists.

The album closes with "Then She Kissed Me", a re-worked and masculinized version of The Crystals' 1960's pop classic "Then He Kissed Me". It was the second cover song to appear on a KISS record.

Love Gun, like other KISS albums from the 1970s, was packaged with a free promotional item. In this case, a paper "Love Gun" was included. The album also came with a KISS merchandise order form. Love Gun was the second KISS album to ship platinum, and would eventually achieve triple platinum status.
