Denied.
A PK is not an administrative punishment like a ban, it's an in character consequence for IC actions.
PK appeals are not accepted simply because you apologise or regret the situation, especially when those actions clearly put you subject to the PK guidelines.
In this case, you admitted to breaking Fear RP by pulling out your gun while you were under gunpoint and were going to get arrested, which directly led to the PK. That alone justifies the outcome.
You also mention that you were trying to ask an OOC question and did not recognise that someone was attempting to initiate RP. However, pausing or disregarding RP whenever it's inconvenient is not acceptable.
If you have an OOC question or need clarification, the correct procedure is to make a ticket in game so staff can assist you.
Furthermore, someone trying to arrest you is not "Fail RP". If you believe a rule is being broken or the situation is improper, you should report it by making a ticket in game and staff will handle it.
You should not escalate the situation by drawing a weapon or refusing to engage in roleplay.
While I also appreciate that you're new to the server, the rules apply equally to all players.
Your time invested in your character and your intent to follow the server rules are noted, but they do not undo the consequnces of the IC actions you decided to take.
