    I was putting a lower together today and I got to the last step. All I had to do was install the front pin, spring, and detent pin. I decided that walking 10 steps to get a razor blade was too much work, so sure enough I shot the pin up at the ceiling. I heard 6 bounces. Never found it. Grrrrrr! I think I have a few more at my office. Don't be lazy. Use the right tools.

    Place the receiver in a one gallon zip lock bag when installing the pivot pin, spring and detent pin.

    I use a 1/4" clevis pin as a tool.
    Insert from the left.
    Insert the spring & detent pin through the hole in the clevis pin.
    Depress into the receiver with a 1/16" Allen key
    Rotate clevis pin 1/4 turn, while removing the Allen key.
    This captures the spring and detent.
    Push the pivot pin in from the right, displacing the clevis pin.

    I think you need about a 2" length pin. There are commercial "tools" available, for an inflated cost. These are available at any decent hardware store for less than $1

    I just use a 1/4" punch. Put the spring in, then the detent with the punch slightly wedging the detent against the hole and push the detent the rest of the way in with a flat tip screw driver and the punch will keep it captured until you push the punch out with the pivot pin from the other side.

    But anyway, I buy my small parts from DSGArms. They usually have all small parts in stock and shipping is not absurd like other places.

    I also put grease inside the pin hole, it gives just enough bite on the spring and detent to keep it from shooting up to the ceiling. A good blade helps as well.

    I am lazy about using the Ziploc (great idea BTW) so I just use the lazy man method. Whenever I buy anything online gun related I just add 2 dents and 2 springs to my order.

    Yep, I took a detent to the eye once. That sucked, it's hard to find a detent on carpet with one eye watering and hard to open :rofl:

    So far I have been lucky to not launch one.
    The same can't be said for a 1911 recoil plug. Those can be down right painful being propelled by and 18 pound spring.
