The new slide frame is available in Silver or Gloss Black, the trigger is precision crafted from Delrin, and slides like butter! The pull is very short, and snappy. An 86* slant makes this comfortable, and easy to use. Comes with integrated snatch grip and beavertail.
The Chipley Custom Machine J2 Slide Frame is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
