Out of the box a Glock comes with a 5.5 lb trigger that is quite crisp after some take-up. Most 1911's come out of the box with a 5-6 lb trigger. The same as a Glock, but without the take-up. A Glock "FEELS" different, but the actual pull weight is the same.
It is fair to say that a 1911 trigger can be modified or designed from the factory with a much better trigger. And some target versions of the 1911 do come from the factory with a better trigger. But a typical 1911 designed for combat is very comparable to a Glock.
It is possible to modify a Glock trigger to be lighter, but in my experience the standard factory 5.5lb trigger feels better and I don't shoot the ones with 3.5 lb triggers any better.
If you've spent years shooting other designs, there is a learning curve to adapt to a Glocks grip shape and the trigger feel. But I've never seen anyone who couldn't master it if they tried. When our local PD made the switch to Glocks it was only the older guys who struggled. For younger cops with little experience, they immediately saw scores improve. Once the older guys mastered them, they found their scores eventually improved too.
