WD,
Think of it as a DAO wheel gun with a really light trigger pull and a slide.
Just remember the 'light trigger pull' part.
As for the whole Glock trigger safety thing, ask Plexico Burris how well it works. He can show you the scars!! (But only on Sundays between 8 and 11.)
I never did understand that one. The man made millions for playing football but couldn't afford a $20 Uncle Mike's IWB holster with a belt clip??:wacko:
