Missing "Packing Heat" acheivement in Destiny.

I did some searching around on the Destiny forums over at Bunge.net and it looks like there are many other users experiencing the same problem. While I couldn't find a exact solution, I did find this:

"If you have a trophy or an achievement that did not unlock, double-check that you completed everything that needs to be accomplished in order to unlock the trophy or achievement. There are often several specific things that need to occur or be equipped
for a trophy or achievement to unlock.


It may also be an issue of your Trophy or Achievements list not refreshing. Simply sign out of your PSN or Xbox account, start the game, and sign back in to your account when prompted from the main screen. Additionally, you can try signing into your
console or system, then sign into your character and go to Settings > Log out of Destiny ('Change Profile' for Xbox One) and press start at the launch screen when prompted.


If you are sure that you have completed everything necessary and the trophy or achievement is still not unlocking, and refreshing your list did not solve the issue, you will need to retry the trophy or achievement. Unfortunately, there is no way for
us to manually unlock trophies or achievements.



Networking or connection issues may delay the appearance of your trophy or achievement. If you don't see your trophy or achievement appear immediately, it may appear at a later date."

Let us know if any of that solved your problem. You could also try posting in the Destiny forums. You're more likely to find a solution there as the users there are more experienced in dealing with Destiny related issues. https://www.bungie.net/en/Forum/Categories Hope
this helps!

Sorry to hear it. Can you please try the following while you are logged in?

Once your character is loaded press the Start button and scroll left. Choose to sign in with a different profile and when the option pops to choose a profile, choose yours again. Hopefully when your character is loaded the achievement should pop.

Hey there, Senoetius! For any issues with achievements, you will need to reference
this sticky. If the troubleshooting there doesn't help you out, you will want to fill out the survey in Phase 3. Once a full investigation happens, you will receive an email response.

If you have already filled that out, please be aware that there is no time frame until you get a response. Once the investigation has completed, you will be sent a response. There is no need to contact support again, make another post, or fill out the survey
again. Rest assured that once we have looked into everything on our end, you will get a response.

Thanks for understanding!

To unlock achievements in Destiny sometimes it's necessary to log out of the game and log in again.

Go to the in game settings and choose change player. Log out, and then choose your profile again. As soon as you have choosen your character and it is loaded completely the missing acheivements will pop up.
