I would like to know what you men with the Glock 20 10mm use as a recoil spring weight....the stock 17lb. spring or a 20lb. spring.

I want to be able to shoot maximum load rounds from 180gr. to 220gr. as well as 165gr +P. Of course I still need it to work with lighter rounds like 155gr 175gr.

 

[S.P.F.]

My G20 uses the stock spring, and it works well with everything I have put through it. The only reason I could see going to a stiffer spring is if I were trying to solve a problem. Do you have any problems with heavy ammo? Like, is the frame taking a beating in front of the slide lock?

Not at the moment. Just wanted to know if the G20 would run better with the heavier spring with some of the heavier loads.

I use a 20# and tried a 22#. My G20SF is the only Glock I feel better with a heavier spring to keep it in battery longer. It also solves the problem of the brass being thrown into the next county. The 22# worked the way I wanted it to but was an annoying weight when racking the slide. Yes, I did have a problem.

I run a 22lb Wolff recoil spring for the full power loads I shoot from Double Tap or my own reloads. I have shot these loads from a 17lb stock spring, and it will work. However, if you utilize a stock spring with full power loads, and chrono it, you will have a wide deviation of velocities. The reason being, with such pressure from the full power loads, the slide will begin to unlock several milliseconds premature, resulting in the spread of velocities.

It would only have to stand, if the slide begins to unlock premature, the stock spring would need beefed up a bit. With that being said, I have run normal "weak" 10mm Federal loads through the gun with the stock 22lb spring and cycles just fine. As mentioned, the 22lb spring is slightly more tough to cycle by hand when compared to the 17lb spring.

Here is my two cents, while I do not typically qualify to carry my G20 on duty, I would run the stock spring for duty or everyday carry with full power loads. The thought being the easier to manipulate spring would facilitate the many alternate methods of charging the gun should an arm be taken out in a fight and a reload be needed. A few (if not numerous) full power loads in an emergency will not hurt the gun and I would place the stronger spring in for target shooting when the added muscle to work the slide is of no concern.

I too have also wondered about this. Ill be shooting Underwood 180grs through mine and wondered if the factory RSA would hold up to it. I have to qualify with what I carry so I would have to shoot the Underwoods.

I have found the found that the stock 17lb RSA in my Gen3 G20 works well with everything from very light Tula .40 S&W in a conversion barrel all the way up to Underwood's 200 XTP load.

I have a Wolff guide rod with various weights of their springs from 17 to 24 lbs. I found that the slide went into battery slowly with a 24lb spring while shooting an older load of Underwood's with a 180gr at 1240fps. This was with a somewhat light grip. After that, I've stayed with the stock RSA as it works well with a heavy to just barely gripping the gun. The good thing is that it has never had a malfunction no matter the spring and ammo combination.

At least one other individual on 10mm fireararms forum found that when he used a very tight grip, his would not function with heavy loads & a heavy RSA. He found it most reliable with a spring weight lighter than stock.

If your gun is reliable with heavier springs, it will probably be easier on the gun with the heavy loads.

I have a G20 Gen3. I put a 20# spring in it from day one. I bought the G20 to shoot heavy loads. I haven't experienced any failures. But I have 7 Glocks all bought new, and never had a failure in any of them From G42 to G20. I can't say that with my wife firing them. She had failures with the G42 until we worked on how she held it and that went away.

Thanx for the replies gentlemen.

Since they are easy enough to swap out I might as well have both assemblies 17 and 20lb. and see which the gun really likes with each round.

 

[UtahG20]

Just tried a 24lb spring in my gen 4 G20. Several issues. Stock
spring works fine with hot loads.

 

[GlockFanBoy25]

I've found more consistent velocity with Underwood loads using the 20 or 22lb loads.

 

[G20 Guy]

I still use the stock spring in my Gen 4, no problems shooting Buffalo Bore's heavy cast bullets or the lighter stuff....

 

[4949shooter]

22 and even 24 pound for Underwood ammo.

 

[ewetstone]

Some of you mentioned Underwood ammo.

Which of it is recommended for SD/carry?

Buffalo Bore....?

 

[LASTRESORT20]

22 # springs work fine with everything for me....as well as the stock 17 # springs...

Buffalo Bore....?

The Buffalo Bore are mainly used for the deep woods hunting aspect with the 10mm. I carry the Underwood 180gr GDHP in my Gen4 29.

The Underwood 165 grain Gold Dot also makes a nice carry load, if you like medium weight bullets.

I personally like the 200gr XTP's for woods carry and SD. Nothing wrong with the 180gr GDHP or XTP bullets for around town, both feel less snappy than the 165gr GDHP's. BB seems overpriced.

Bought a 20# captured RSA with stainless steel guide rod from Brass Stacker when the gun was new that has functioned perfectly and hopefully saved some hammering on the frame.

I have a G20 with 2 slides 10mm, 1 stock and 1 for competition shooting. They both use a 17lb spring, but I have just ordered a stainless steel rod and a 20 lb spring fir it. I also have a GL21 custom slide that uses a stock 17lb spring. So I believe it should be fine with the 17lb. I do shoot hotter loads as well as 180 in 10mm. And the 230 grain 45acp's . and the 27 is good for me.
