You might check here for the recoil spring. www.buymilsurp.com  Mine was an OEM new old stock part.

Thank you for the info. May I ask what is the color of the spring ? The spring that I have, the original one, has a deep blue color. The one I recently bought has a stainless color but as I told you it's too tight . Another question if I may..
What is the OD of your barrel ?

It definitely was not stainless.  It looks just like the original recoil spring.

Here is a picture from the website and what I received looks just like it.

As to the OD of my barrel - not a clue.  I don't own a set of mics.

I have test fired a standard 15lb Wolff Springs recoil spring for a .380 Walther PP in my CZ70 and it would cycle fine with and without the suppressor.  Today I tested the heaviest spring they make for the .380 PP (18lbs) and it also cycles with the suppressor on.  I can't fire it in my backyard without the suppressor so I don't know if the heavier spring will cycle the second shot without the extra back pressure created by the can.  I'll try to follow this post up tomorrow weather permitting. 
I'm going to keep the 18lb spring in it because it delays the slide slightly and makes the pistol much quieter with the suppressor.  I'll sell the standard 15lb spring for half of what I gave for it if anyone wants it.  I only shot six rounds so its practically new.
More info to come.

This is very interesting cgreen ! Especially the 15lb recoil spring. Did you try this spring with different brands of ammunition ? Does it fit without any modifications ? Please keep us informed.
Thank you very much !

 Wolff,   .380 Walther PP  16 lb  recoil spring .

It arrived last week and I tested it last weekend. I used 3 magazines , 8 rounds each.

One magazine loaded with Geco 73 grains FMJ, one loaded with Sellier & Bellot 73 grains FMJ and the last magazine loaded with

Geco and Sellier & Bellot , mixed.

Not a single malfunction, of any kind, occurred
