Instructions

    • 1

      Remove the magazine from a full-frame Sig Sauer P250. Make the weapon safe by pulling back the slide, and inspecting the firing chamber.

    • 2

      Convert the P250 -- in a caliber such as 9 mm -- to a compact 9 mm by pulling back the slide. Push the take-down lever on the left side of the weapon while holding back the slide. Guide the slide forward, and off the slide rails on the lower frame of the weapon.

    • 3

      Pull the take-down lever out and away from the lower frame of the Sig. Grip the slide rails, and pull back the hammer. This pulls the frame assembly up and out of the lower full-sized module.

    • 4

      Insert the frame assembly -- removed from the full-sized frame module -- into a compact-frame module designed for 9 mm and .40-caliber ammunition. Insert the back of the assembly into the compact-frame module, and pull back on the hammer. Grip the slide rails. Push the rails down and back to lock the assembly in place in the compact-frame module. Insert the take-down lever into the frame module; turn it to the "down" position.

      Select a compact 9-mm slide assembly. Line up the back of the slide with the slide rails, and slide it onto the weapon. Pull the slide back; rotate the take-down lever to the "up" position. Guide the slide forward to complete the conversion process.
