well the main thing about the glock is the trigger safety...that is the reason people dont like or think they are not that same.

i thought that as well before i actually got one.

but after playing with the safety to see how it reacts. you actually do have to have that safety pulled flush with the trigger for it to disengage the safety.

and they make a slide lock for the trigger safety that is cheap and really easy to install.

not to mention the glock is like the honda civic of handguns. you can do everything to them lol
