Ruling authority:John Amidon

Question
Can I use any after market magazine in my gun for Production? Also, may I grind off part of the base pad on my S&W M&P?
Ruling
After market magazines are allowed in Production, as long as they are dimensionally the same as the original magazine for that model gun? In other words, you may not use a Glock 33 round mag in an approved Glock gun, regardless of only loading 10 rounds in it. Grinding on the magazine base pad, would be an external modification and not allowed, the magazine when inserted, is a functioning part of the gun and the base pad is external.
