For those who may not know. The takedown lever was removed, but there is still a takedown procedure. Pull back the slide and move the hammer drop lever to the down position. Release the slide slowly and the tail of the hammer drop will lock into the deep cut in the top of the hammer, positioning the slide stop at the right point for takedown. Turn the gun on its left side, pull on the end of the recoil spring guide, and the slide stop will fall out.
