Glock 21sf guide rod and spring

[Ant45]

My G21sf .45 shoots and feels fine, any reason to change the guide rod & spring to something fancy like the stainless steel or tungsten? Will this be an change that actually does give results like the 3.5 trigger connector ? (I did notice that improvement) or am I to curse the internet for too much info?

I know I know, I've been reading to much and like to buy crap because it's fun.

Voices of reason please chime in.

What sort of "results" do you intend to get by changing the guide rod? Too many people replace parts just for the sake of replacing parts, even though those parts may not serve any purpose at all. I say stick with the factory one.

That's just it, I have no results that I know of that I want. It's my first Glock so I'm just poking about seeing what I can learn. Like I said above the 3.5 trigger connector was a worthwhile improvement even though I thought the stock trigger wasn't that bad. At least I got something tangible for a mere $25.

I understand the desire to "customize" guns; it's something I used to do when I first started this hobby. But nowadays I feel that most of that stuff is just a waste of money, and am more than satisfied just having a gun that's more or less stock and works reliably. If I do replace parts, it's only when I have a specific problem that I feel needs to be addressed.

Does it work and is it reliable?

If yes don't change anything.

If no, fix it or sell it and buy something that's reliable.

Nope.

The stock 17 pound spring will work fine. I change it every 2500 rounds. Not expensive.

The one advantage to a heavier (tungsten) rod guide is a bit less muzzle rise from recoil. Adding weight up front will reduce muzzle rise and help you get back on target faster. Is the added weight and fractional reduction in muzzle rise worth the added cost? That is your decision.


While using a reduced weight may very well help the gun shoot a bit flatter, it will also increase the likelihood that the frame will be battered by the side. The factory engineers developed a total “system” that works well. Changing one component can easily create a situation where one or more components do not work as designed.

I have a stainless guide rod and 22lb ISMI flat spring that I use when I shoot hot 10mm (with the G20 slide) and with 45 Supers in G21SF mode.

There is no difference in function using this RSA, other than the 45 Auto loaded brass lands very close by.

Stick with stock until you decide you want to shoot 45 Super.

I shot one of my G21SF's today (with both the G20 slide, heavy RSA and some hot 10's and the G21 slide, stock RSA and some light 200gr LSWC's, the 45 Auto loads felt like shooting a 22LR after the mighty 10's).

Have fun.

I have a stainless guide rod on my 17, 21 and 20. I do not notice any improvements over the stock plastic rod. The only reason why I have/use them is because I have different weight Wolff springs. If Glock offered different weight springs with their plastic guide rod, I would have bought them instead (unless they cost more than the Wolff springs and guide rod).

Leave it alone. Just because some yahoo starts selling something, does not mean it is any good. Likely you will venture too far, and end up ruining something you should never have touched in the first place.

Frames are already battered by the slide. I don't really care about a system, or how Gaston Glock wants me to use my weapon. I know lots of guys who shoot a lot with reduced recoil springs with no ill affect. I just looked at the frame of a Glock 17 that has an 11 lb recoil spring since the fall of 2013; indistinguishable from new.

I hate to say it, but even though your responses are often terse, I recall that with exception of a few posts where you were a jerk, everything you post is correct.

This however isn't good information. You're not providing ammo specs, and a simple visual comparison is inadequate, you're not measuring or quantifying wear on any components, let alone providing round counts or maintenance schedule.

A frame should not be "battered." You're saying a 55% reduction in spring tension is perfectly fine for all factory ammo?

[Sheepdog1968]

I,wouldn't change anything except for the sights I personally like on defensive firearms. Take the money would up would have spent on ammo and save it for a defensive firearms class.

[teg33]

No need to change anything other than sight. Glock is perfection

I have the same weapon. Had glockstore do a level 2 trigger job and tungsten guide rod. That being said. Eh. Tungsten rid nice but not 50 bucks nice. Just toss in a glock 3.5# minus connector and break it in.

[nbirnbaum2]

Oh. 25. Cent trigger help helps tons if you haven't done it
