I know people swap out the guide rods and springs in a Glock 20, but do they also do that in a 29? If so, why, and with which strength spring and which guide rod? Thanks!
If you are going to be shooting standard factory ammo (watered down) then I wouldn't change a thing. If you're going to be loading your own "real" 10mm stuff or DT & BB then I would go up to a Wolff 21lb spring.
