Overwatch Precision does not provide a specific pull weight for their Polymer DAT Drop-In Trigger Kit but state it provides decreased pre-travel, and reduced break weight. I'd recommend reaching out to them directly for more information.
My Gen 3 Glock 19 has this trigger and it’s a consistent 4.5lbs, but in a strange way feels “lighter”…perhaps it’s how consistent the break is or how the wall feels, snappy reset, who knows. I’m comfortable with it as a carry option as well. All safeties are not tampered with.
For the Gen 5 it doesn’t say in the description but I was also looking to add this trigger to my Gen 3 29 and in the description on it says that it reduces the trigger weight by roughly 1 pound. A stock Glock trigger is typically 5.5 pounds so just say 4.5 pounds. Also I have found that if you change the connector out on it for a 3.5 like you would a stock trigger than it feels to me like the trigger gets a little sloppy and it gains back some of the pre-travel. I have not yet tested the weight but it definitely feels heavier than the stock trigger with a 3.5 pound connector. This is all coming from a Gen 5 17. Overall so far I like the trigger.
