Ship that was for older 1st gen guns some 2 need help but very few. I took mine out of box ran break free on slide rails and went to shooting 50 rounds S&B ball did same with #2 gun next day.
Only thing you need to learn is to let trigger go all way foward so fully resets other wise you will have a lite primer strike.
This takes a couple mags of fast fireing .at least for me.
Now on gen 2 the sights are black so you can make any color you want. Since this is close up pistol I painted front orange and left rear alone. I shoot a little low and about a 4" group at 10 yds.
Use a small screw driver to remove pin and keep fingers on each side or pin as popping out. Just like manual says.
If you get the 380 you might get the 11 and 13 lb recoil springs from wolff Their for 32 but work in 380. Might tame recoil some.
I shoot S&B in mine for play and of course Corbon for SD(see loki corbon results) in 380 the DPX is proving to be the best .After all Mike Shovel at Corbon said that was the test gun for the 380DPX.
Both of mine have been flawless Uncle Mike #1 pocket holster is correct one.
