I am considering having my HK USP either hard chromed or coated in NP3. I really like the look of a bright hard chrome, but I have heard that NP3 wont show scratches as readily even though it is softer than hard chrome, not to mention the added teflon gives it quite a bit of lubricity. My HK is used strictly for work and CCW, and gets bumped around quite a bit, so durability is my main concern. Any suggestions, opinions and/or photos would be appreciated.
