It sure looks like the Recoil Master system in STI pistols. For those who know, just how close are the two different systems? The effort needed to move the slide assembly to the rear seems to be measured in poundage. What is the poundage ratings of the dual recoil springs in the G 36 system? Usually, it seems that recoil springs in short/fast moving slides need replacing more often. If true, how long do the springs on YOUR 36 last before giving up the ghost?
