As Monty said: Put in a NY1 (8 lb.) or NY2 (12 lb.) trigger in your Glock, and you're basically carrying a semi-auto with a revolver-like trigger. I think this is your best bet, since you said you like Glocks!
But most importantly: Be most diligent in making sure you're aware of keeping your finger off the trigger at ALL times until DIRECTLY on target; make sure to have a holster that completely covers the trigger guard, and make sure nothing is sticking out on your clothes or holster that could snag the trigger. Always SLOWLY reholster your pistol with care.
Follow these rules 100%, and you'll have no problem with a Glock... even
if they have a light trigger. This is what it's all about: Being responsible in handling a gun, and not relying upon other mechanical devices for "safety", simply because we would lack confidence in ourselves to not follow the basic rules of firearm safety!
Even after thinking my post over, and not going for it... then there're some manual safety's on the market for Glocks; you'll have to install them yourself, or have a armorer do it for you... of course.
If you like 9mm, then I suggest the sub compact Glock 26; if you like .40 S&W, then I suggest the sub compact Glock 27; if you like .357 SIG, then I suggest the Glock 33; if you like .45 (though GAP), then I suggest the Glock 39.
If you don't mind a little bigger size than these, then I'd suggest the .45 ACP Glock 30 (or G30 SF, if you can find one).
The most power in a compact - sub compact size: The 10mm Glock 29... loaded with DoubleTap ammo, of course.
