Oversized Magazine Release
PDN is at the workbench with three different models of handguns to examine their magazine releases. Of all the modifications you can make to your defensive firearm, an oversized magazine release is one of the most useful. Making the release larger will almost always make it easier for you to hit it, especially under stress.
My experience is purely competitive , IPSC handgunning of 20yrs. The other situation, not mentioned in the video, where accidental mag releases can occur with O/Sized buttons, is during left handed shooting. Might be worth mentioning to check that. If your right hand becomes inoperative?
What kind of sites are on the Glock?
