TM1 still not running reliably.
I've polished and lubed everything that moves in it.
After researching magazine fixes here in this forum I found the following issue with my magazine:
The areas pointed out by the top two arrows are the contours of the feed lips which appear to properly confirm to the cartridge contours.
The areas pointed out by the bottom two arrows are the "throat" of the feed area which I found to be too tight so I opened them up a bit with needle nose pliers and polished all the edges with a Dremel.
Dummy rounds now glide out of the magazine effortlessly with thumb pressure, which they didn't before.
I'll be making another trip to the range today and will report back here...
