I know its a little off-topic, but I am trying to get some data on different loads that you use and what you believe is the optimum spring rates for glock pistols. Some background: I have been doing some computational modeling with the slide-springs on Glock pistols and seem to have found values that work very well to predict recoil springs needed for a certain load or to predict stovepiping with under-powered loads. So, far the data matches well with G17, G19, G20, G21, G34 data. I have read that many people feel the 17lb factory recoil spring is undersprung on the G22 (and possibly G23). Has anyone played with the recoil spring and determined if there one that works better for factory ammo (around 400ft-lbs energy). If you have favorite spring / ammo combinations, it would be great if you could post the data (need spring rate, bullet weight, and velocity, what pistol). Also, does anyone the actual mass of a G22 slide/barrel/recoil spring assembly? I am estimating the combined mass at 546 grams. Once I get some data to make sure the model works well, I will share results. -Dana Wanna kill these ads? We can help!
