Assembling a pistol frame

Assembling a pistol frame

To begin, we suggest using a new, American-made LPK. We only use U.S.-made LPKs.

Start by placing the mag release spring into the frame.

Once you secure it in the cutout, install the mag release button through the right side of the frame. Use a pick or flat-head screwdriver to carefully pry the top of the spring far enough over until the magazine catch locks into the notch but becareful.

Make sure to test it to ensure it works properly. Contact us to learn more about assembling a pistol frame.

Insert the tab of the connector into the right side of the trigger housing. Then, bend the connector outward slightly. After that, connect the trigger spring to the hole in the rear of the trigger housing.

Next, place one hook of the trigger spring into the trigger housing so it forms an S shape. Subsequently, attach the other hook of the spring to the hole in the trigger bar.

Now, rotate the trigger bar down into the trigger housing. Once you insert it into the housing, rotate it slightly so the wing on the left side enters the slot just behind the ejector on the housing. Finally, rotate the trigger bar back into place.


Here’s the revised content with sentences trimmed to 20 words or fewer:


Insert the trigger into the trigger hole of the frame. Then insert the trigger housing into the rear of the frame.

When the trigger housing is halfway in, adjust the trigger bar beneath the connector tabs. Finish inserting the assembly.

Now, insert the trigger housing pin into the hole in the backstrap of the frame. Ensure the pin is flush with the hole.

Slide stop: With the straight leg of the slide lock spring facing down, insert it into the front of the frame. Ensure it seats in the cavity.

Next, insert the slide lock with the ridged side facing rearward and the flat side facing forward.

Make sure the slide lock spring sits in the notch of the slide lock. Depress the spring and slide the lock over it.

Ensure the slide lock moves freely.



Locking block: With the legs facing forward, insert the locking block into the frame and push down until the holes align.

Insert the locking block pin into the top hole of the frame. Use a punch to maneuver the pin just below the surface on both ends.

Insert the trigger pin from the right side of the frame until you reach the second notch.

Next, insert the slide lock into the gap to the left of the trigger. The hook of the spring should face up. Push it forward until the holes align.

Once aligned, push in the trigger pin. Ensure the pin sits just below the surface on both sides.

Good job—you’ve finished!
