ISMI Glock Spring and Guide Rod

[C4IGrant]

I recently decided that it was time to do a little PM on my G19. So I bought an ISMI spring and SS guide rod.

To tell if the weapon recoiled differently, I first shot a couple mags with the old spring. I then installed the new guide rod and spring and ran a couple more mags. The gun felt smoother during recoil and allowed me to be faster on follow up shots. I will be running several hundred more rounds through it to make sure there are no issues with combo.

Do you have the factory Glock barrel or an aftermarket??

I've always wanted to try one of those. How is the spring held captive on the guide rod? Is that a screw on the end of the guide rod?

I do not have any Glock barrels.

Dave, there is a screw at the end that captures it. I degreased the screw and put loctite on it and cranked it down.

Grant,

What's different about this setup that could lead to those results? The guide rod is heavier I'm sure, but what about the spring?

Grant,

Who makes the guide rod?

Thanks,

Mark

I think it is really about the quality CS spring. My weapon also had about 8k through it as well so the stiffer spring simply reduced felt recoil.

Hey Mark! guide rod is made by ISMI as well.

On a side note, I know the Glock is a "plastic" gun, but I just feel better having a solid steel guide rod VS a plastic one (call me crazy).

How much are they for a Glock 23?

I'm interested also in the SS guide rod and ISMI sping. I've seen the ISMI flat wire recoil spring comes in 18# and 22# for the G19. Which one are you using? With what ammo?

I am running the 18 and shoot Winchester white box, S&B and UMC for training.

I bought the ISMI CS spring and a tungsten non-captive guide rod for my G17 about a year and a half ago. No problems to report as of yet.

I’ve heard that the tungsten guide rods tend to crack with high round counts, but it will be a while before my round count makes this a concern for me.

edit: to correct my thought.

Tungtsen is brittle. Dawson Precision makes a tungsen rod for 1911s that has a stainless cap (end toward bbl link) that's a whole lot less likely to break (just the rod portion is tungsten). Its held together with a screw. I don't know if the offer the same for Glocks. My STI has a tungsten rod all one piece (not Dawson) so it's just a matter of time before it cracks. I carry a stainless rod in my range bag for when it gives up.

All, I now have these captured guide rods and springs in for all Glock mid and large framed models.

I've actually felt quite the opposite. I lighter spring reduced "felt" recoil to me.
