These were on my SIG for a while before I swapped them out for another set of sights. They're the TRUGLOW TFO Tritium/Fiber Optic sight set, #6 Front and #8 Rear, and are in excellent condition.

Here's the Ebay link: https://www.ebay.com/itm/27304233733...84.m1558.l2649

Or, if you'd rather purchase directly here, I'd take $75 shipped.
