I was informed about this company and their Pull The Dot IWB Loop 'alternative' which was designed by Brian Okuden, who's been making knife sheaths for 20 years and current OEM for Spartan blades. These sights are rather unique, to say the least... surprised I've not seen or heard of them before. The photo is their 'speed' model and they also have a finer precision sight.
