If you go to Wolff's web site they offer replacements & I think they identify original equivalent weight.

Thanks, I found it there : 7.5 lb
I'm still wondering what the correct round count recoil spring replacement interval is for the model 41.

Look for the right way to install a Wolff spring, it will look backwards compared to a centerfire. As I recall, the closed coil should go toward the muzzle.
ETA. The factory spring is closed at both ends.
If the open coil of a Wolff is at the muzzle, it will work its way between the guide rod and the slide causing a monumental hangup. Or so I have read on this board.

Pay attention to what J WATSON said ,or you will be in deep **** with your M-41
Also, please disregard the instructions that come with the Wolff recoil springs for the model 41. The instructions are wrong.....the open end of the spring has to go to the rear, as others have mentioned.
Remember also that if you have to clip a model 41 closed end recoil spring to gain reliable function, be sure to place the clipped end (open end) into the rear frame recess....NOT at the front.

If you are not in a hurry Brownells lists the factory spring but they are currently out of stock.
You could also try calling S&W and asking if you can buy one. They used to have an online store to sell things like that but closed it down a few years ago. They Wolff springs are fine as long as you put them in the right way but I would rather have the factory spring.

I have posted this warning many times here on the Forum. ALWAYS install closed (finished) end facing the muzzle!
ALSO: Beware some Youtube video's are incorrect - including the one that the Crab-apple "Gunblue490" made. He inserts the spring with the opened end forward - WRONG! I did not bother contact him about this as he doesn't like any comments that don't praise him and just deletes them. He can learn the hard way as far as I am concerned.

Wolf springs
Years ago I bought a kit of wolf springs for an M1 carbine. It was supposed to be a perfect match and correct.
Out of the 10 or so Wolf springs, I used exactly one. The rest were simply assorted commercial springs that were close but no cigar. Never again.

Some model 41 spring notes from another forum.
New Factory Recoil Spring
4.67" long
0.029" thick wire
36 coils
0.270" diameter ends
From past notes a Wolff Reduced Power spring pack has these springs:
6.0# - 0.027" wire
6.5# - 0.028" wire
7.0# - 0.029" wire
7.5# - 0.030" wire
My M41 runs very well on CCI SV and Eley Club with a Wolff recoil spring with these dimensions:
4.55" long
0.029" think wire
36 coils
0.272"/0.277" coil ends

I recently bought a new Model 41 PC. It only would cycle with some high velocity ammo and even then, would not eject for the first round in every magazine. I tried four different .22's and had some trouble with all of them. Finally, I got the Wolff 3 spring pack with a 7, 6-1/2-, and 6-pound springs. The only one that worked well with CCI Standard Velocity was the 6# spring. I still have a FTE about once every 150 rounds.
By the way the direction of the springs is critical. The closed end of the Wolff springs must go towards the muzzle because the other end of the spring aligns with the space between the guide rod and the hole it goes through. If you fire it like that the spring end might get wedged in that space and it would really damage your gun. The factory 7-1/2# spring is finished (closed) on both ends and won't cause that problem. Helpful hint: I painted the open ends of all the springs with different colors of my wife's fingernail polish, so I know which spring I am using and that it is visible when the barrel is removed.
Also, be aware that in the 3-spring pack from Wolff, the 7# spring was not correct, it was an inch longer that the others and the original. I called Wolff and they sent me another 7# spring, but that was still much longer than the original and the other two Wolff springs. Be wary. I'm just going to use the 6# for CCI SV and not worry about it.

Or stronger ammo. I gave up trying to get my 41 to work properly with standard velocity ammo and just shoot high velocity ammo in it now. A little less accurate but very reliable. CCI Blazer normally but sometimes MiniMags. If you are shooting in matches and need to extract every last bit of accuracy getting your 41 to work with SV ammo makes sense. If you just want an accurate, fun to shoot and reliable 22 handgun try a few types of HV ammo and use what works best in your gun.
If you are worried about increased wear and the possibility of many tens of thousands of rounds of HV ammo eventually cracking the trigger guard that also acts as slide stop note that a weaker spring will have the same effect. Years ago I bought a 3D printed buffer that stops the slide to protect the trigger guard but when I tried to buy a couple of spares could not find a source.
If you have other 22s that case of CCI standard velocity does not have to go to waste. I find it shoots very well in most 22s, just not my very finicky 41.

From what I just read here, I think using factory springs might be the best bet.
It's weird how some aftermarket parts work in one kind of anything but not in another. We used to see a lot of older Chevrolets with the small block V8 come in with engine misfires and found nearly-new Champion spark plugs installed. Replacing them with AC plugs cured that ill. At first, we thought one of the Champions was defective or had been cracked during installation but when we saw this numerous times, we became believers. As a breed, there's nothing wrong with Champion spark plugs but they just didn't seem compatible with the SBC engines.
I'm sure that Wolff springs are not problematic in most guns.
