Why is that? If you divide malfunctions into feeding malfunctions and extraction/ejection malfunctions, then someone designs a pistol (the P7) that will extract and eject WITHOUT an extractor, you then have a very reliable weapon. My gun can function without an extractor. Can yours? My gun will function with a broken extractor hook. Can yours? My gun will function with a weak extractor spring--or with no extractor spring. Can yours? Do you see my point? Extraction issues are quite common, even among allegedly reliable guns. The P7 has no such issues.
To ask a person to deliberately take a functioning part out of a pistol to prove it's unreliability or reliability is silly.
