Mateen legally purchased a Sig Sauer
SIG MCX semi-automatic rifle and a
9mm Glock 17 handgun,
[113][114][115][116] the two firearms later used in the shooting, from a gun shop in Port St. Lucie two weeks before the shooting.
[117] He also attempted to purchase
body armor, but was unable to do so as the store where he tried to make the purchase did not sell the product he sought.
[118][119] Several weeks before the attack, he attempted to purchase body armor and 1,000 rounds of bulk ammunition at another gun shop, but the staff became suspicious of him and turned him away. A salesperson at the shop then said he contacted the
FBI, but federal officials said they had no record of such a report, and the local sheriff's office also said it was unaware of the incident.
