So I guess no ones had any experience using the Galloway Precision Steel Spring Guide Rod assemblies without issue or with issues, that's what I was asking? A lot of gun owners and Glock owners change parts out on any gun they own at any given time whether it be a $500-600 Glock's or $1500-2000 1911's, its all personal preference really that's it, if someone has even just one bad experience with a plastic part on any gun and they can get a steel part in place of that said part that would never have had that same issue as its plastic counterpart at any given time whether it be 100 rounds or 10,000 rounds down the tube, a lot of times that's what there going to do is replace it with the steel part or stronger part. But that's not my point here in this post originally, it was a question about a parts function because they are a fairly new aftermarket part for the G43 and they are $35 compared to The Glock Stores $79 Tungston Guide Rods. But just so everyone knows, as of now my Galloway Steel Guide Rod Spring Assembly arrived yesterday and I went to the range today with it and fired 300 rounds with it in the gun with no issues whatsoever, I got the 10% decreased spring (due to that's the one you want if your going to be shooting factory manufactured ammo mainly most of the time not +P or reloads etc..) it actually feels no different than the stock factory spring really during firing, felt recoil feels pretty much the same and racking the slide feels good to chamber the rounds as well, I switched them out back and forth a few times to see if I could tell any difference between them and I could not other than the fact that one is steel and one is thin sheet type metal in places with a plastic rod. For some odd reason I seemed to be able to get back on target easier and seemed a little more accurate with the steel guide rod in the gun, I noticed that the factory guide rod shifted off the barrel easier than the steel guide rod did which to me is not that good of a thing, the steel guide fits just slightly snugger in the gun (not so much as to be a bad thing but a good thing in my opinion). So I'll be keeping the Galloway Steel Guide Rod Spring assembly in my G43 for now and keep the factory one as the back up one as I have done with other guns and Glocks. Thank you everyone for the opinions and posts.
