Getting back to the original issue....
I took the LImited back to the range today. Short story is that the MAGS STILL DROP ON EACH SHOT (arrrggghhhh!!!). I had two mags and 'adjusted' the top lip of the mag cut on both. I did a little, tried again, repeated... until both of them were too wide to go into the gun. Back off a little with a 'love' tap... still no go.... so
I think either the mag release either doesn't have enough material on it to hold or there is just too much verticle play around it due to the cuts and the recoil moves it down. Guess the next step will be next week and try to shim it to remove the verticle movement... will wait until after that to call EAA...
Once again, thanks for all of the input so far.
