Which pistol malfunction is commonly caused by a dirty magazine or weak feed?

• A. Stovepipe due to ejected shell lip.
• B. Failure to feed (dirty magazine or weak feed).
• C. Double-feed (two rounds).
• D. Misfire/delay (ignition issue).

Answer: (B)

Failure to feed is the malfunction most directly tied to the magazine and the feed system. The magazine’s spring and follower push rounds upward and into position for chambering; if the magazine is dirty or the spring is weak, the next round may not be reliably lifted or held in line, so the slide can’t successfully chamber a round. This results in a failure to feed, where no round is properly loaded into the chamber on cycling. Other malfunctions come from different parts of the cycle: stovepipe is tied to ejection dynamics, a double-feed involves two rounds trying to feed at once due to lip or ramp issues, and a misfire/delay is an ignition problem. Keeping magazines clean, inspecting for wear, and replacing worn magazines helps prevent failure to feed.
