I am looking for spring sources for a future purchase 4516-2 that I saw in a local gunshop. Before I purchase I want to make sure I can re-spring it and have spare recoil/mag springs.

Wolff only has springs and spring kits for the 4516-1 and Brownells and Midway are sold out of most 4516 parts.

Should I hold out for a 4516-1 or are new springs available somewhere?

Thanks for your help.

The 4516 should use the dual spring setup, I've only seen them available from S&W, although Midway and Brownells usually stock them. Wolff doesn't make a replacement but I don't understand why as they are used on almost all 40/45 compacts.
 
The 4516-2 uses a dual nested recoil spring. These same springs are spec'd on some 14 different compact .40 & .45 models. I've noted that part numbers 108660000 & 108670000 have been out of stock everywhere I checked for quite some time now. I haven't spoken with S&W for quite a while so you might try calling their C/S line and see if there's any in stock or at least get an update.

I'll Not be stymied by the lack of factory springs so, I've been using one of these in my 4516 for the last couple years.
ISMI Glock Compact 20lb Recoil Spring G19,23,25,32,38
It functions flawlessly.

I just ordered 1 of these.......... and I just put a new dual nested recoil combo in my 4516-2...plus I have another spare set.....why?.....I really don't know....I do know that it is my second favorite range gun behind the 4506-1:D...and my P220:o

You can use this single spring in place of the -2's dual springs? I've bought several used guns recently that use the dual springs & can't get these springs to get them to a good known starting state. (I'm starting to feel these dual spring guns are a liability if S&W isn't going to provide common parts, like this, for them.)

That's what I've been doing for some time now. I have been using a 20# in my 4516-1. My SSV project gun has been permanently modified to use these springs and I bought a big bag of 30 coil 22# springs made for compact 45s direct from ISMI to keep that gun happy. I also have one of those 30 coil springs trimmed to 27 coils in my Shorty45 for evaluation. And just to prove it works reliably, I turned a custom guiderod and tested a fullsize ISMI flatwire in my 4566TSW, The gun functioned flawlessly with a ISMI 20# and that spring is still in there.

I had resolved to address the spring issue when I was nearing the end of my 4516-1 melonite project. I wanted to replace the single spring with something readily available that replicated the capacity of the nested springs in the newer 4516 revisions. I found the flatwire springs that ISMI manufactures for the Glock compact models a perfect fit. As the supply of nested springs has dried up I've installed ISMI flatwires in other guns while holding my small stash of nested springs in reserve.

The ISMI springs are made to fit a guiderod no larger than .250" diameter. The guiderod on a 4516-2 or for that matter, any of the other fourteen or so models that use the nested springs is .236" The flatwire will drop right in and is as near a perfect fit in the spring tunnel on the slide as well as in the frame as one could hope for.

For a unaltered 4516-2 I'd probably start with an 18# spring. Monitor the ejection pattern and have a 20# on hand in event the gun needs more spring. My 4516 likes a 20# best likely because I lightened the slide somewhat and brass drops consistently about four o'clock and six feet away.

Should S&W be too busy hawking their plastic wares and happen to never again supply the nested spring sets... I don't care, I'll keep my real steel guns happily running anyway.

Replacement for dual recoil springs

Thanks! That's good to know info. I have a 4013 & 4056TSW that have been waiting for dual springs. I'll give these a try! (Now if my ejected brass would just behave & quit bouncing forward of the firing line & taunting me. :rolleyes:)
 
Bill - thanks for taking time to develop that little work around and then taking time to share it with the rest of us. That's a trick that deserves a sticky and I hope the mods notice it.
 
Before Bill suggested an alternate spring, I e-mailed Sprinco.com at [email protected] and asked if they would consider making 4516-2 springs. The guy has e-mailed me back twice for further information and seems interested in producing a recoil set.
That would be nice. If S&W doesn't supply him the specs he will need an unfired specimen to work off of.
I'll keep you posted.

When I asked if he had any and if not could he make one, he replied:
"I don't, but since it is no longer a factory supported item, I just e-mailed a friend who is tight with a lot of folks at S&W, and he's going to ask if they would be willing to cough up a copy of the original design drawing for the spring. Otherwise, we would have to have a new unfired sample of the spring in order to replicate same. Will advise if he can come up with something."

I believe his friend is a member of this forum.

I heard from Alan at Sprinco. He is interested in creating a spring set for the 4516-2 but needs our help.

He contacted Simth and Wesson attempting to aquire an unfired dual nested spring set in order to copy the specs. Alan relates, "While there is still one guy looking around in dusty corners, S&W gets rid of everything 8 years after production ceases for a particular model."

Alan wrote, "unfired specimen samples of both springs would be required in order to establish the design loads for the springs. These would only be borrowed, tested, and returned unfired."

Alan was also interested in some measurements if anyone can help him there, I dont have calipers.

"We would also then be able to design a Recoil Management System to be used in conjunction with the larger outer spring. The possibility also exists, depending on the guide rod diameter of the 4516-2's vs. the original 4526-1's that the current offerings from Wolff could be used with one of our Recoil Management Systems and the inner spring would not be necessary anymore. You could probably have someone on you forum measure the diameter of the spring tunnel on the slide of an -0 Variant as well as the I.D. of the exit hole of the rod in the front of the slide and provide same for your -2 specimen."

If anyone is able to help him he can be reached at: [email protected]
 
Forum member RobsTV posted this link to 4516 dual springs just the other day, from Numrich:

https://www.gunpartscorp.com/Manufacturers/45Series-35290/4516-34097.htm?page=1

I ordered 2 pairs myself from the same link, and they're on the way now. Total cost, with shipping, about $18.

These will be for my Shorty 45 and 457.

If I'm missing something here about compatibility with my pistols, someone please let me know; otherwise, I'm thinking this is an easy-peasy-Japanesey solution to the springs issue. :D

I saw that link too and appreciated it. However when I went to the site, they were sold out of the outer spring already.

It would be good to have a company produce new springs as opposed to selling the few remaining examples of new old stock.

The 4516-2 was designed to use two springs, one that nests inside the other. I cant help you with the compatability of your model, but I am sure someone on here can, and will.

Well, if it'll be any help, once my two sets come in, I'll be glad to share one of the sets so the fellow can get dimensions off of 'em. Just let me know where to send 'em.

If you have an unfired dual recoil spring set for the 4516-2, Alan's mailing address is:

Alan Dugger
Sprinco USA
7804 Danz Blvd.
Austin, TX 78724-2508

Alan is looking locally for a 4516-2 so he can determine the installed height of the spring when the slide is in battery, and the maximum compressed height of the spring when the slide is fully retracted in order to establish the load heights. He is also hoping to prototype a Recoil Management System.

I dont know anything more about Sprinco's Recoil Management Systems, but I am encouraged that their might be additional aftermarket products for these Gen 3 autos.

Thanks, ap. I expect the springs here on Monday, and I'll send a pair to him right away. I'll PM you when I do, so you can let him know they are on the way. Like you, I'm encouraged by the prospect of aftermarket products for these pistols.
