Pros:

-Dual Magnums = The fun has been doubled
-Very well done
-Right number of rounds in the magazines
-This mod supports other magnum skins already installed
-Pretty perfect if you want to have fun

Cons:

-Don't know why, every pistol in the game turns into a magnum (could be a pro, but many people prefer normal pistols .-.)

Conclusion:

Just need to fix some very little bugs, overall it's perfect.
