| When I install the hammer/trigger pins, does it matter which way I put them in? Each pin has two grooves... does it matter if the groove near the end is on one side of the receiver or the other? On my first build I simply followed the illustration in the assembly guide but someone asked me if it specifically mattered. |
| The trigger pin only matters if you have done the 15 minute trigger mod or for some reason shortened one leg of the hammer spring. In that case, the groove in the trigger pin must be on the same side as the long leg of the hammer spring to keep the pin from working out during use. If you have a normal hammer spring there is no incorrect way to install the trigger pin. The groove in the center of the hammer pin locks into the j spring in the hammer so the groove near the end of the pin doesn't do anything. Just as the groove in the center of the pin doesn't do anything when installed as a trigger pin. The pins are identical, just built for dual purpose and manufacturing ease. |

It's a way to (theoretically) reduce trigger pull weight and smooth out the trigger. It involves cutting one leg from the hammer spring (obviously) which reduces hammer tension on the trigger. But it also reduces hammer energy. I don't endorse it at all. On the other hand, using some valve compound on the mating surfaces of hammer and trigger is quick, cheap and easy, and really smooths out both surfaces without the possibility of damaging anything. It's messy, but just a little. |
