I got back from the pistol range today and had my workbench lit up with my new LED fixture and saw this: Those 'dots' inside the grip are from the blowback I believe during ejection. Correct me for bad terminology - but those dots of unburned powder are coming out of the magazine! Somehow the gasses get into the mag and blow out the holes where you can see how many rounds you have left. This is the first time I noticed this - but it took those LED lights to make it pop out to see well. I imagine that the spring and follower gets bathed in hot blowback. Do you think this is the only place those gasses can get out since I plugged up that grip-void with a plug - you know: the hole behind the magazine....!
