4013 nested Recoil setup conversion to ISMI Flat Spring Question

[reddoggm]

Ok doing all the reading here on this topic I,m seeing that You Folks are using 18lb-20lb 31 coil springs My question is that the Factory rating is 16lb,s according to Wolfs Web Site Are You Guys just going extra power or is that needed to keep from battering the Frame going to the single spring ? I have an ISMI 15lb here for a 1911 compact build that I put in my 4013 and it feels almost as stiff as the Factory nested Springs It has No issues with spring bind hand racking
According to Wolfs Single springs for this Gun a 15 would be a reduced power spring
(From Wolfs Site)

Recoil Spring
For Use in:
4013*, 4014*, 4053*, 4054*, .40 S&W
4516, 4516-1, 4536, 4556, 4596, .45 ACP (Call for 4516)
* Not for Rev. 4, dual recoil spring models.

Reduced Power...: 15 Lb.
Factory Standard.: 16 Lb.
Extra Power........: 17, 19, 21 & 23 Lb.

Another Question is are the nested Springs rated differently than the single Spring setup ?
And lastly Is anyone running the ISMI,s without issue on the .236 Guide Rod ?

Here's some additional info on ISMI and other spring options:


https://www.google.com/url?q=http:/...ds-cse&usg=AFQjCNEu5baS5jQXLznbtPJcg5k6a0N4UQ


I'm using a heavier Wolff single spring (20lbs) in my 4053 (larger guide rod) in order to slow down the slide/ejection cycle and reduce/eliminate slide to frame contact. (battering)

In my 10mm conversion slide/barrel combination on the same frame, I'm using a nested configuration with an OEM inner spring, and a heavier Wolff (21lb) outer spring. I have not tried the ISMI springs as yet, as this current setup seems to work. Ejection is nominal, with empty casings landing approx 6ft away....and "battering" is not existant, as I have the springs set up with the ammo I'm using so the slide will lock back after the last round, but just barely.

Hi Carter thanks for sharing your experience with me that gives me other options I,m going to order a few ISMI springs and I already have some heavy Wolf singles here and get to testing I,ll Post back with my results soon as I get the ISMI's
as always Thank You Sir

Just to clarify, you have a 4013 (non-TSW) rev.4 ? (The Wolff specs you posted are for the 4013 (non-TSW) rev.1)

I have a 4013TSW that I use the ISMI GLC-20 spring in, with no problems.

I also have a 4013 (non-TSW) rev.4 that I use the ISMI GLC-22 spring in, with no problems.

I don't recall ever seeing poundage specs ever listed for the nested springs, either individually or as a pair. It's not on their packaging. S&W had some in-stock several months ago.

Sprinco makes a nested replacement spring (#45162) set that's listed in their Tactical Spring section.

I gave Sprinco/Alan a list of all the models that spring set replaces but he hasn't updated the webpage yet.

4013TSW
4053TSW
4056TSW
4013 (R4)
4014 (R4)
4040
4053 (R4)
4054 (R4)
4516 (all except -1)

4553TSW

Hey BLUEDOT Yes I have a non TSW must be a rev 4 It has a .236 guide rod and Nested Springs I was assuming that being all .40cal bullets basically being equal whether Low or High power that Having a nested setup or single spring setup they would require the same strength in the recoil system I mean that lets say 1 wimpy spring slipped over a medium strength spring (nested) Or 1 stiff single spring so I guess I am assuming wrong here that a 16lb spring is OK being singled but going to the nested setup which I believe makes it a progressive setup You need to go heavier on spring tension
Please correct me if I,m missing something Thanks for the other spring Info also

I wouldn't say going from a nested to single necessitates a higher poundage. Some of us prefer a heavier than factory spring since we shoot upper end loads mostly.

Since the 4013(R1) had a 16# single spring (.290" guide rod) it would seem reasonable to assume the 4013(R4) with nested springs (.237" guide rod) equalled it. The nested springs probably gave it a different rate curve.

Try some different weight springs & see what works best for you & your ammo. Springs are pretty cheap.

Yes Sir that is the plan Try some different springs and Test until I find what works best for me
I like the Idea of the single spring setup I,m an old 1911 Guy and when i started acquiring the compacts with the captured nested spring setups I successfully converted all but my EMP to singles and got them to Run a lot better than the factory recoil system on most of the 1911 compacts the recoil setups are one piece not allowing changing spring pressures easily so when I set them up with a single setup at least I could test the waters for recoil control that's why I was interested in what You guys were doing with Your Smiths but the difference being I can at least mess with different spring poundage with the Smith nested setup I really like the flat wire springs they seem to act more like a progressive system I think I,m going to go that way to start and if I can get it working right I,ll stick with it but if not You Guys have been very helpful with alternatives that are working so no matter which way I go there is a proven solution Thanks a bunch for the Input
