Same problem with a new 41. Shot fine with all factory parts but when put in a lone wolf alpha wolf barrel with ss guide rod and #22 spring immediately dropped magazines including one that was new. Replaced guide rod with factory rod but kept lone wolf barrel and continued to drop magazines. Had a friend who has glocks shoot it and same result. This all with hardball. Will try again with factory barrel and guide rod but fear will have same result. Should also mention that pulled mag catch and could see no wear/rounding, etc. This is my first glock and have been shooter for over 60 years. Not too impressed!
