Noobish question, I know. Forgive me.
Pretty straightforward question though: Which would be better weight recoil spring for the pistol? It will be fed a diet of Underwood 200g XTPs and TMJs.
I was pretty sold on the 22lb recoil spring until I read the reports of it being under-sprung by about 2lbs.
Well the Gen 4's have been seeing issues with the higher impulse ammo, Glock has been trying to address them.
I know that some have even had issues with aftermarket springs as well. The aftermarket gen 4 springs are different from to older versions of gen 3 and gen 2 G-20's
Now with that said , I run a non captive Wolff RSA and 22 lb spring in my G-20 SF and it runs like a sewing machine...with loads matching the UW and my own handloads. ;D
I run the same setup as shadow, flawless
On the flip side...any harm with a heavy 24 lb spring slamming the slide home with more force causing problems/premature wear?
I don't completely understand the mechanics and physics at play when the slide returns home.

How are the GlockMeister ISMI RSAs? Seems as though they offer a pretty reasonably priced Gen4 compatible single spring for the G20 Gen4. The guys at Underwood suggested a 22lbs one when I talked to them.
What do you mean? They are ISMI springs on a Glockmeister rod. Are you asking about the spring are the guide rod?
Also, please try not to derail my thread too hard :)

It's a bit rude to ask a totally unrelated question before the question the OP had ask had been addressed.
But...it's the internet after all...no big deal. :D

No, I completely agree, it was my bad forum etiquette , so I removed it, hoping not to derail the topic. I am also interested in the end result on your question!

Copy. Hopefully we get an answer.
OP,
Have you shot your G4 G20 with the factory spring setup? Has it given you fits? If so, was it manufactured before 1/1/2014? If it was, contact Glock; there were some issues and their website has info on getting an updated RSA.
If you haven't tried it with the G4 RSA, you may want to before expending the extra $$$$ without necessarily needing to. My G4 G20 has handled all the Underwood loads with no issues or frame battering.

Post 1/1/2014. I have not shot it yet. I am being far more OCD than I generally would be because I have a full FDE model and I imagine it would be a PIA to try and have it replaced should something happen.
Good to hear that your G4 20 hasn't had any issues with the stock set up. How many rounds have you fired and what types of loads?

No problem.....I was just letting you know the RSA for the G4 has ungone some modifications by Glock.
I've shot 250+ of hot loads, Underwood/BB type loads; then approx 500+/- target loads, mainly Georgia Arms, but some other brands, too.
I believe Redbaron is correct...the stock RSA may work for you. I would suggest giving it a try.
If not, the 24 pound RSA from Glockmeister has been working without a hitch in my Gen 4 and Underwood ammo.
I run a 22lb with a 6lb stricker spring as well and all is great.

What does a heavier striker spring accomplish?

I think a 22 or 24lb spring would both likely serve me well.
My new question however: any harm with a heavy 24 lb spring slamming the slide home with more force causing problems/premature wear?
I don't completely understand the mechanics and physics at play when the slide returns home.

Not that I have seen. I have 2400 hundred rounds through my Gen 3 20 and 800 rounds through my Gen 4. I just had a Glock armorer look at both guns and there was no mention of battering or premature wear.
Though....I haven't shot only Underwood, PBR, and Buffalo Bore through them. I mixed in some medium to light stuff as well.
22lb and 24lb ISMI recoil springs on Gen4 Glockmeister SS guide rods came today.
Objectively the stock dual RSA and the 20lb ISMI do NOT feel any different in terms of racking the slide,'
One thing I did notice: Racking the slide w/ the ISMI springs installed was making a funky scratching sound- the spring was scratching the barrel.
Is this normal? I'm not worried about cosmetic wear on the outside of the barrel but the sound was pretty abrasive and did not sound "right".
Glockmeister was out of their SS Gen4 guide rods for a few months because the last batch they had were machined out of spec and had to be remade...I'm hoping this has nothing to do with it.
Just make sure the spring is seated properly. The scratching sound you are hearing is probably the spring scratching against the SS guide rod.
You won't notice much of a difference by feel. The difference will come in the performance of your gun with hot ammo. At least that has been my own experience.

This is good to know. I have a 20# ISMI captive RSA right now, but I've just been shooting factory "hot" loads like Underwood and Buffalo Bore. I may step it up to 22 or 24#, if it seems like the guns getting beat up after I start loading this caliber.

I took the RSA out and hand compressed a few times and you were right 100% of the noise was coming from the spring scraping against the steel guide rod.
Lubing the guide rod also helped tremendously.

Interesting. I've heard people say it is noticeably harder to rack the slide with a 24lb spring, figured the 22lb would be just a little harder than stock also.
You might be able to tell the difference. I noticed it more with my Gen 3 really. I didn't notice much at all with the Gen 4 working the slide by hand.
