Somehow, it often happens that it looks and feels so pretty at the store, and not so much so when you get to the range I have 2 Bodyguard .380's and they are not exactly the same, But both "warmed up" with a bit of shooting, initially the trigger pull on both was on the tough side.

You might want to take it to the range with a box of low cost ammo, and exercise your trigger finger. Then, take it home, clean it carefully, a couple drops of lube, and see what that does. As noted, both of mine improved with a bit of use.

You can certainly swap out the springs and they are available from Galloway Precision and others, but doing so will crash your warranty on the spot. Better to send it back, especially if you're not equipped to do the work properly. They are very easy to work on, but you do need a few simple tools and a pin block to do it well.
