A Smart Part-Liebenberg Designed Pistol Dynamics ISS 1911 sight system

Paul Liebenberg is a smart guy. After shaking up the custom 1911 world while an innovator at the famed Pachmayr gun works in the 80's, at the S&W Performance Center in the 90's, or now at his own Pistol Dynamics, Paul is always brimming with ideas. IMNSHO One of his best ideas is his ISS interchangeable sight system.
In his words:
Our proprietary interchangeable sight system (ISS) is the only fully secured
replaceable front sight design available for the 1911. This unique design relies
on a precise press fit of a dedicated dovetail sight to a matching longitudinal
dovetail machined into the slide. The front sight is also trapped by a retention
tab integrated into the design of either a solid or spherical Pistol Dynamics
keyed bushing. The fit of the front sight to the slide is precise enough to
ensure that the sight will not dislodge during field stripping and cleaning. A
tombstone-bushing wrench is supplied with the system. Numerous front sights
options are available that include height variations and a myriad of inserts.
System includes one standard front sight ..............$195.00 installed, plus
shipping The ISS System is available as a factory install only. We will need your slide and barrel assembly in order to fit the system. Please call for a compatibility check before mailing your assembly.
This is a VERY slick setup and allows easy front sight changes in the field depending on conditions and/or height adjustment depending on POI. Brilliant! My Ned 10mm wears this sight. I love it-I would change all my guns over if I could.
