It has often been stated that Glock tends to" over spring" the recoil springs to handle +P loads reliably ... In the case of a G17 Gen 3 the stock recoil spring is #17 pounds . For factory target loads (Blazer , American Eagle , etc.) what would be the ideal spring weight to drop down to for better ability to cycle and get back on target in gun games such as IDPA ? *I'm thinking somewhere around #13 lbs. to #16 lbs. (Wolff) would be the range for factory target loads (custom reloads I'm sure would be down around #11 lbs. ~ #12 lbs. possibly) ... Your experiences with factory 9mm target loads and ideal reduced recoil spring weight ? ... Thanks in advance !
