Both find what they're looking for. The 18-round magazine capacity is notable for a .45, and owners regularly mention it as a competitive advantage over traditional 1911-pattern guns. Reliability and build quality reviews are positive across the board. The recoil management at 31 oz gets credit, and the night sights perform well in low-light practice. The threaded barrel and ambidextrous safety are functional rather than cosmetic. The price draws some discussion. Most buyers consider it reasonable given the feature set. Night sights, threaded barrel, and FN build quality don't come cheap. Aftermarket support is more limited than for Glock or M&P platforms, which is a consistent theme across FN products. Weight is occasionally flagged as a downside for all-day carry, though the 31 oz is in line with similarly equipped .45 pistols. ## Pricing **13 offers available** | Vendor | Price | |--------|-------| | Guns Com | $941.99 | | Buds Gun Shop | $959.99 | | Kygunco Com | $987.99 | | Gunbuyer Com | $999.00 | | Grabagun Com | $999.00 | | Shootingsurplus Com | $999.00 | | Selwayarmory Com | $999.00 | | Globalordnance Com | $999.00 | | Primaryarms Com | $999.00 | | Gritrsports Com | $999.00 | *...and 3 more offers* ## Similar Products - [FN 545 Tactical .45 ACP Pistol - Night Sights, FDE Finish](https://gunsnation.com/p/fn-545-tactical-45-acp-pistol-night-sights-fde-finish/UCEt9uKNs) - [FN 545 Tactical .45 ACP DAO Pistol - 10+1 Matte Black Finish](https://gunsnation.com/p/fn-545-tactical-45-acp-dao-pistol-10-1-matte-black-finish/UCEt9uKNb) - [FN 545 Tactical - Optic Ready, Threaded .45 ACP Pistol in FDE](https://gunsnation.com/p/fn-545-tactical-optic-ready-threaded-45-acp-pistol-in-fde/UCEt9uKNz) - [FNX-45 Tactical: .45 ACP Night Sights, Threaded Barrel Handgun](https://gunsnation.com/p/fnx-45-tactical-45-acp-night-sights-threaded-barrel-handgun/UCEt9uGXY) - [FN 510 Tactical - 10mm FDE Pistol, Threaded Barrel, Optics Ready](https://gunsnation.com/p/fn-510-tactical-10mm-fde-pistol-threaded-barrel-optics-ready/UCEt9uKMl) - [FN 509 Tactical - 9mm, 4.5" Threaded Barrel, Night Sights](https://gunsnation.com/p/fn-509-tactical-9mm-4-5-threaded-barrel-night-sights/UCEt9uIw3) --- *Data from [GunsNation](https://gunsnation.com)*
