Glock all the way. I prefer my Glock fully loaded in a Serpa II holster with an addition of a trigger block safety. Reading the site www.glockleg.com
, one can't be to careful. Lol
While the chamber being empty, gives a simular result, it lowers the available rounds by 1, and is more difficult to present than removing the trigger block.
Recently became a Glock certified armorer, and I am more impressed with the male tupperware that goes boom, than ever. They are built wonderfully, and make very long lasting sidearms. I have a G20 that is in its third decade, not one complaint.
