M1 garand clip latch
This is a "standard" Garand malfunction which can be caused by a number of things:
-worn clip detents-try another clip
-weak clip latch spring-replace spring
-worn clip latch-replace clip latch
-bent follower rod-replace follower rod
-worn follower rod forks-replace follower rod
-worn operating rod catch-replace op rod catch
worn follower arm-replace follower arm
follower rod rubs clip latch-replace follower rod,clip latch,or op rod catch
I would try replacing the clip latch spring first(least expensive).Also ensure that critical points are lubed with proper grease.Garands can be frustrating sometimes.Recently had a problem with one failing to engage the clip.I swapped out all related parts until I found that the follower rod was the cause-not in the malfunction "book"
