JA-NINE Firing Pin Change
Unlike most of its brethren, the firing pin on the JA-9 is held inside the slide with a retaining pin.

1. With an unloaded gun, field strip and prepare your tools - a 3/32" punch and a small ballpeen hammer.

2. Locate the retaining pin hole on the left rear of the slide, place your punch against the pin and tap, left to right, with ballpeen until the pin starts moving. Note: It was difficult to hold punch squarely with one hand and take pics with the other! Make sure punch is in line with the retaining pin.

3. Position rear of slide over the edge of the work table, continue tapping punch until retaining pin clears the slot in the takedown button inside the slide's firing pin bore. Remove punch, being careful to apply pressure to the spring loaded takedown button - if not, it will fly across the room!

4. Remove broken and/or separated firing pin from slide, and place new firing pin, along with the spring and takedown, into the rear of the slide in the order shown.

5. Start retaining pin back in from right to left. Push takedown button into place so that the retaining pin can pass through the slot.

6. Continue tapping with ballpeen, right to left, and set retaining pin flush with outside of slide. Set firmly with punch and one moderate hammer blow. Pin should be slightly recessed when done.

If they don't trust us with guns, how can we trust them with the government?

"If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen". Samuel Adams,
