Range-used Springfield Echelon 4.0C with Holosun 507C

Hi all,

I'm looking to purchase my first firearm. I went to the range recently with a buddy and we tested out a few firearms and I really enjoyed the Springfield Echelon that I fired. I was talking to the owner of the store and he offered me the exact gun I fired. I was wondering 1) if anyone had any advice on purchasing a range-fired gun and 2) what does everything think is a good deal to take on the firearm. I was told it was poor etiquette by my friends to disclose the price, so I was wondering what others think would be a good deal on it + any further requests/questions to ask the range before purchasing it.

For context: I'm looking for a new gun to both conceal carry and for the range. The gun was a Springfield Echelon 4.0C with a Holosun 507C that has been on their range for the past 6 months.

Thank you all for helping out! I appreciate it!
