I’m putting together a new USPSA Carry Optics gun and want to run a 15lb recoil spring. However, every aftermarket Gen6 guide rod I can find says they aren’t recommended for the G17, and only for the 19/45, I believe it has something to do with how the guide rod protrudes into the longer 17 slide, but I’m not sure. My understanding is that the Gen6 19/45/17 all use the same factory RSA, so this is a little confusing.

How are you guys running reduced power recoil springs on these? I read somewhere that a person removed the end from the factory polymer guide rod and ran it with an uncaptured ISMI spring. Are there any other options?
