Some terms are easy: Clip vs. Magazine. However, others are more subjaective: A 10 round 1911 magazine is high capacity, a 16 round Glock is standard, and a 10 round M&P is a low or limited capacity. We need to just become comfortable with industry and manufacturer terminology and use it. Like talking sex with your kids: Use the proper terms, don't cringe, don't giggle or smirk, and don't act ashamed.
No matter what we say or how we say it, our words will be spun. If we stick to the accepted anyone can defend against their spin.
