Looking for an easy to use weapon for a female and had a question about the differences in the "AS" vs other models. The new "AS" I looked at has an extended magazine release which I am guessing is longer to facilitate easy release. How much harder is it to release a magizine with the shorter release? Any other differences that I didn't notice such as easier slide manipulation? Or does "AS" only stand for the DA/SA trigger pull. Thanks from the newbie.
