I just got a brand new M9A3. After disassembling, cleaning and reassembling, I noticed the following issue:
1. I am unable to cycle the slide over 50% of the time. The ?locking block? gets stuck and doesn't fall down. As a result the slide can't be pulled back. If I pull back the slide slightly, pause for a second, the block will fall, and allow me to pull the slide back.
2. During firing the pistol doesn't cycle. I am assuming this is due to the locking block being stuck.
Did I miss something in reassembly?
Here is a link to an album with a video illustrating the issue and some photos:
