Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the ...
Introduced in late 2017, Ruger intended to use the Security-9 to replace the Ruger SR-Series.The Security-9 managed to be even less expensive than the SR-Series as it eliminated the adjustable backstrap and ambidextrous magazine release, used an internal hammer-fired mechanism instead of a striker-fired mechanism and hardened aluminum alloy rails instead of steel rails.
