I bought my plastic guns so I wouldn't scratch up my Colt 1911's. Took me a few brands/models to find CZ's and end up with something that matched the Colts for reliability and accuracy. My P07 and a modified CZ 75 Compact are regular carry guns. Shopping, driving are hard on the P07. The Compact gets carried for yard work, dog walks, garage work, crawling around in the dirt/grass/gravel/concrete (garage). The P07 gets carried kayaking/fishing.
I don't throw them in the dirt/mud/gravel just because I could. I clean/inspect/lubricate them when they've been abused by carry conditions.
I don't neglect anything (not for cleaning/inspecting/lubing but I have guns I never pick up, talk to, or shoot - why waste time on something that doesn't shoot good groups when you have guns that do shoot nice groups??)
There are marks in the finish on both of my regular carry guns. I can't carry/hunt with one and not mark it up (for some reason). But I don't abuse them on purpose.
