STI Costa VIP .45 ACP

Nearly-new STI Costa VIP in .45. This is the commander-size with the 4.15" (or maybe 4.25") barrel. Gun has been owned, shot, and carried since early December. Round count is exactly 530, including 85 test-fire rounds shot at the factory. This pistol prints VERY tight groups, but I want a 10mm. I'm open to partial or complete trades. I'm especially interested in a Tanfoglio Witness Polymer Compact in 10mm. Sale includes: factory plastic case, three disassembly tools, five Recoil Master replacement springs, and a total of six magazines: two 11-round, four 9-round.
