Just started learning the 2e rules, and I have some questions around Ranged combat.

1) Is there no Ranged into Melee penalty anymore? I only see penalties that would apply to cover for not having a clear shot.

2) With the removal of most attacks of opportunity, is there no penalty for using ranged weapons in melee? I don't see a point blank shot feat anymore ..

The description of the Pulsecaster Pistol is:

"A smaller version of an arc pistol, the pulsecaster sends a low-energy blast at its target. This blast stuns the target without dealing serious damage."

There is no crit listed in the table for it.

If you hit a target with the Pulsecaster Pistol, will they gain the Stun Condition?

If Yes, how long is the target stunned for? The stun condition and weapon description don't offer guidance.

Thanks
