I do have a tungsten rod guide in my Glock 34, with a factory weight 17 pound recoil spring. To be perfectly honest, I do not know if it really makes much of a difference. There is no question that it is significantly heavier than the stock plastic one. Does it make a difference, I really don’t know, although I haven’t tried to do any sort of real test. The theory is that more weight up front should cause the barrel to raise a bit less in recoil and recover faster. Perhaps it does, but I guess I am just not able to notice the difference, with the range ammunition I use.
Now having said that, it works just fine and is 100% reliable, (around 12,000+ rounds with no issues) so if you have a few extra bucks to burn, why not. It certainly does not hurt anything.
I try to make it out to the range at least once a week and go through on average 200 rounds per session.
