What steps should you take if a firearm fails to chamber due to a misfit magazine?

• A. Stop, check for proper magazine seating, try a different magazine, and inspect magazine lips and feed lips for damage.
• B. Continue firing and fix later; no need to check magazine.
• C. Replace the firearm.
• D. Change to a larger caliber.

Answer: (D)

A misfit magazine can prevent a round from aligning with the chamber, so the safest and most effective response is to diagnose the magazine itself rather than the firearm. Stop firing and ensure the weapon is pointed in a safe direction, then remove the suspect magazine and verify the chamber is clear. Re-seat the magazine firmly or try a different, known-good magazine. Inspect the magazine lips and feed lips for any damage, deformation, or wear that could be preventing proper feeding. If the problem persists even with a good magazine, test with another reliable magazine and check the firearm for other feeding issues or contact maintenance. Changing to a larger caliber or replacing the firearm does not fix a misfit magazine and can create unsafe conditions.
