Great information, thanks! I recently installed a stock guide rod with captured spring from a Gen 3 G34 in my P10F. It seemed a little short but seated well in the gun. I test fired 10 rounds to check function. No problems. Based upon this I ordered a guide rod and an uncaptured 15 lb spring that should arrive this week. Description indicates it will fit G17 and G34. I may have to trim length of guide rod but do not expect to have any issues with function. I will post results once installed and test fired.
BTW, I have now shot the gun in 4 USPSA matches with no issues. Gun runs flawlessly and I love it. Recoil spring weight is a little heavy for my 130 power factor loads is why I’m going down this path. Also have a 13 lb recoil spring on the way assuming no issues with rhe guide rod and closer to factory 15 lb spring.
