Galloway offers 15, 17, 20, and 22 pound recoil assemblies, but no 18 pound. On their site, they say the 17 pound is the stock spring weight. I could swear that S&W told me before that it was 18 pounds. I'm going to call them and see if I can confirm that but I was wondering if anyone here had already confirmed that with S&W.

Also, I was wondering if anyone here had tried both the 17 lb and the 20 lb Galloway recoil assemblies in their SD9VE, and what the results were.

Thanks.

Is there a problem with your stock recoil spring?

If not, I wouldn't worry about it.

M jus saying...

No, there is nothing "wrong" with the polymer recoil spring guide rod/assembly...I just prefer steel. When a pistol I buy comes with a polymer guide rod, and if a steel rod is available, I always replace it with the steel rod. So far, except for the SD9VE, these haven't been captured spring assemblies (the Beretta 92FS and the Ruger LC9 are two examples that come to mind) so I could reuse the same, stock recoil springs. Pistols like the M&P series already have a steel guide rod in their captured assemblies.

I feel the same way about full length guide rods in 1911s...I always replace them with GI guide rods and plugs, if possible (government and commander length models; not possible on compact or other models with bull barrels, etc.) Again, it's just personal preference...although I do find the GI guide rod easier to field strip than the FLGR.

18# is stock S&W on Sigma/SD recoil springs.

Whether you can use the 20# depends on your ammo.
The empties should land 3 to 6 feet away when your recoil spring matches your ammo. Too light tends to batter the frame, and too heavy tends to give feed problems.
If you get the Galloway set up right, it will work as well as the stock spring. However, piano wire springs of any brand will wear out quicker than the flat-wound recoil springs, which is something to consider when choosing recoil springs.
The complete Galloway assembly does have a flat wound spring, and I suggest the 17 # version if you shoot factory ammo, particularly bulk ammo, or handload down around the 130 Power Factor range. Even for hot handloads, 20# is about all you'd want in 9mm. You can wind up with short stroking with the 20# and wimpy ammo.

Thanks! I don't reload, out of consideration for the safety and welfare of others, so I will be shooting factory ammo.

I wonder why Galloway didn't go with 18 lbs rather than 17? I wonder if they'd do a run of 18 lbs? I guess I should ask them that!

I haven't asked them, but I have an educated guess: the steel rods have somewhat more friction than the polymer rods, and make the recoil spring drag a bit. I grease the metal rods in my M&Ps, but leave the polymer rods in the Sigma series dry.

Thanks! I'll start adding a little grease to the recoil assembly as part of my cleaning routine.

I don’t understand this happened while I was cleaning it now the recoil spring want compress or seat image.jpg
