SAAMI Pressure for 9mm

checkfeo · 01-08-2011, 06:46 PM

If the recoil impulse is not strong enough to overcome the main spring tension, the action will not fully cycle (open) to eject the spent case (stove pipe) or load the next round.
If the recoil impulse is too strong, it overcomes the spring tension and slams the toggle against the stops, putting undo stress on the action.

The only way I know to correct either problem is to change the spring or change the pressure in the load. (change ammo)
