Weapon Attachments Info Incorrect

Ok here is a list I'll keep compiling until I hear back. Please remember this is not going to be a complete list even when finished as I have no way to actually tell how much firepower an attachment actually adds. I can only report the mismatched info in the tooltips.
Please also note that we have no clear indication of what the various listed stats actually mean. For instance Firepower seems pretty straightforward to just be bullet/weapon damage. But what about Accuracy and Handling? Various attachments list +Accuracy and - Recoil Control, and show a corresponding +Accuracy on the graph but -Handling. Other attachments list +Vertical or Horizontal Recoil control, and - to the opposite, but the graph shows only +Accuracy. Please give clearer definitions of these stats on this screen.
 

G57:

-GAR45 Suppressor: Lists -Effective Range in text but shows no change to Range in Graphic only a decrease in Firepower.
-Close Combat Mag: Lists -Effective Range in text but shows no change to Range in Graphic.
-Close Combat Extended Mag: Lists -Effective Range in text but shows no change to Range in Graphic.
-Subsonic Mag: Lists -Reload Speed and -Projectile Velocity, and the Graphic shows -Range and -Handling, should Handling be included here? This is a normal sized clip.
-Close Combat Drum Mag: Lists -Effective Range and -Reload Speed and the Graphic only shows -Handling.

Updates to follow as I have more time to not be shooting people.
