I traded for a Glock 21 sf with ambidextrous mag release. The gun looked to have several rounds thru it when I traded it, and I've test fired it and it performed fine.
I've read that the ambidextrous mag release is a problem-as I've had no issues with this is it gtg, or down the road will it present problems?
I actually like the ambi mag realease sans any unforeseen future issues
