As a self proclaimed hand cannon expert I can tell you this. Her Mercy is a good weapon, it will get you by most of the games content. Some dudes even use it for PvP under certain roles cause it has 4 more range than Red Hand IX. It also looks cool, it has a number of things going for it. But the thing is, there are better Hand Cannons. Namely if you don't want the generic Fatebringer response. You got The Fulcrum, Red Hand IX, The Jewel of Osiris, Lord High Fixer and The Devil You Know. Out of all these weapons, The Fulcrum has THE best overall stats of any hand cannon of its subtype in the game, even Hawkmoon. The only thing holding it back is no elemental damage. Now, some people will say that the 8 round magazine is a downer. But it actually works beautifully with the perks Final Round and Luck in the Chamber, you can further increase the odds by adding Smallbore further increasing its stats but not really any downside. The Fulcrum has a ridiculous base reload speed for a hand cannon, using Smallbore will put it at the reload speed of Hawkmoon. Which is still pretty good, so you get the increased range and stabilty, 7 rounds in the magazine with Luck in the Chamber and Final round. This makes it have more damage per shot than Hawkmoon on average. To anyone reading this, The Fulcrum is really that good. Be sure to pick one up before it leaves the vendors because I am not sure a Hand cannon this good is going to be released any time soon. And no, I am not comparing this weapon to Thorn that is the exception. Overall for PvP Thorns subtype of handcannon is generally worse for PvP. And Timur's Lash' variant really is up for debate, people usually prefer the variant first given to The Devil You Know, Fatebringer, Lord High Fixer, The Fulcrum etc for PvP. Here is a list of stats of all the favorite guns in that subtype. http://www.destinydb.com/items/3378827888-the-fulcrum http://www.destinydb.com/items/120524974-jewel-of-osiris http://www.destinydb.com/items/3667595457-her-mercy http://www.destinydb.com/items/3164616407-hawkmoon http://www.destinydb.com/items/3259091099-red-hand-ix http://www.destinydb.com/items/335341128-lord-high-fixer http://www.destinydb.com/items/879791779-the-devil-you-know
