    Quit thinking and buy from here already. Hunter is the man! He will reply to any questions you have quickly and it seems like no matter the day. You can’t beat service like that.
    He once carried my handicapped mother 4 miles when her car broke down.

    Hunter always goes above beyond to help a customer out

  42. Neil (verified owner)

    My second X2 from Hunter, great price and customer service. My package got mis-delivered by USPS to the wrong mailbox in my complex for the second X2 and Hunter was very responsive while I waited for USPS to sort it out.

    Excellent customer service and great prices

  44. matthew d. (verified owner)

    I can buy these products pretty much anywhere with a competitive price, but the human element Hunter brings to the table is priceless and keeps me returning, if I’m going to spend my hard earned cash I want it to go to an independent that’s working hard for his customers. Purchasing from Ibex is a no brainer.

  45. Chandler (verified owner)

    This was the cheapest place I found. Hunter price matched for me, on a holiday. He actually emailed with me and made a coupon code all on Thanksgiving. Shipped out quickly once the holiday was over. Very happy with the product, was easy to sight in, and now my P365 is that much better.
