Guys, I am a USPSA shooter rated a B in Production. I am moving over to Limited/Limited 10 where I can make some mods to my Glock. I am a HUGE fan of the stock Glock. However, in competition with a Glock 35 and major power factor loads, I find I am fighting the gun in recoil as compared to heavier guns (note this is not an issue with my Production gun--a Glock 34 shooting minor power factor). It is not that big an issue, but having to drive the gun slows my splits down. My question is.......how much do tungsten guide rods help control muzzle flip? Is the gun still as reliable as with stock parts? I am in competition, so I am looking for any kind of edge (even slight)--but not if it compromises the reliability of my Glock in any way. I am interested in hearing from those who have actually used tungsten guide rods. Thanks in advance.
