on a new (or old glock for that matter) glock, or on any one...i read somewhere that to test for spring tension(i think that is what it was a test for)..one can hold the glock pointing upwards, purposely take it a little out of battery ....and i cannot remember the rest??? is it supposed to return into battery if doing that? is this a test of the recoil spring strength? i tell ya i tried it and pointing it upwards, and racking the slide back a little to take it out of batter and just letting go...well it just stays there. i tried it on a new glock and an older one with a fairly recent spring. so did i miss something on this test. i swear i saw it here on glocktalk???
