Poundage for Wolff Springs for Smith & Wesson 1000-series 10mm Pistols

[Anthony]

Hello Everyone,

Can someone suggest to me some specific poundages for the use in the Wolff Extra Power gunsprings sold for the Smith & Wesson 1000-series 10mm pistols?

I have a couple of these pistols in my safe that have sat unused for many years because I got tired of the weak magazine springs. Rounds would slip out into my magazine carriers from time to time and they would have to be changed frequently.

I'm interested in carrying them once more for CCW so relability is of the utmost importance.

The magazine and recoil springs are what I am most interested in raising the poundage in, but welcome advice on other types of springs for this gun based on the board's collective experience.

I shoot full power 10mm loads like the Winchester Silvertip and DoubleTap line exclusively.

Thank you for your time and attention.

Recoil springs - 1066, 1076, 1086, 10mm - factory is 17 lbs
- 1006, 1026, and 1046 (should you be so lucky!) - factory is 18 lbs

Mag springs are an undefined strength but sold in +5% or +10%.

I have 5 of the S&W 10XX series and generally use extra power recoil springs, about 19 lbs for most of them. I tend to use their 'calibration paks' and have found out that a couple pounds above factory weight has provided excellent reliability. Some of the guys that shoot DT exclusively will sometimes opt for heavier recoil springs. I shoot a variety, including handloads - so the slightly heavier springs have worked fine for virtually everything I put through them. (If you go much higher than factory weight on the recoil springs you may want to consider installing stronger firing pin springs as well.)

I also use +5% mag springs and have yet to have a problem.

Good luck!

I have been using a 22 lb. recoil spring in my 1066. The reason I chose that one is that it doesn't let the gun try to throw empty (expensive) brass over the horizon or bounce it off my forehead. I am trying for a neat little pile about three feet off to my right, but I don't really expect to get there. I am settling for less than ten feet.

I don't worry at all about "frame/slide battering" due to heavy recoil springs. A heavier recoil spring cannot return the slide to battery any harder than a light one unless the light one is permitting the slide to batter the recoil stops. The worst effect from a too-heavy recoil spring will be failures to feed/eject because the slide does not travel far enough rearward. Whether it is too heavy or not depends on the magnitude of the recoil impulse, which depends on the ammo used.

It is my understanding that a stronger firing pin spring is indicated when you get a "smeared" firing pin indent on your primer. That means that the case is ejecting before the firing pin retracts. Theoretically, this could break the firing pin after some number of repetitions. I haven't found this yet, but I keep the firing pin channel pretty clean, and don't goop it up with excessive lubricant.

My magazine springs haven't given me a problem, but then I rotate through five magazines.
