+1.Make sure you give your new HK45 a good cleaning and detail strip to remove all the packing greese before going to the range. Any factory ammo will work fine in the HK45 as the gun will eat anything you feed it.
Um... I'm sure the pistol will survive, but this is certainly not recommended. Unless you use grease as your regular lube, don't do this!You guys clean them?
This ain't no custom 1911....
The HK45 doesn't come with "packing grease" from the factory. It comes lubricated and ready to go.
I took mine out of the box and to the range where I put 100 flawless rounds through it.
These pistols are tools, not swiss watches. They are meant to run, no matter what.
Go shoot and enjoy.
