Unfortunately Canik TP9 DA (Double Action) hasn't been popular. İndeed it was the copy of Walther P99AS(Anti-Stress Trigger)
. İt has Manual decocker which is unusual for striker fired pistols.
Loaded and Decocked carry is safer.
When the pistol is cocked , the trigger weight is very light and pulling way is short.
When you decock Striker mechanism , the trigger is heavy and long to pull. You could pull trigger multiple times. Other strikerfired pistols are need to be slide pulled. No repeating trigger.
Glocks have bad accuracy thanks to trigger system.
