M11 380 small mag well magazine springs

[ferndog1]

I have 7 steel small mag well magazines for my RPB M11 380. Of the seven one is 100% reliable. The main difference between them, is the reliable mag spring is 2 to 3 coils longer than the others (at 10.75" OAL )

Does anyone have a source for replacement (small steel) mag springs?
Wolff doesn't make them

I had luck just pulling them longer. So far seems to help.

While Wolf doesn’t make a specific mag spring for the small frame Mac style magazine, could you use the dimensions of the mag to find a similar magazine spring that would fit? I don’t know, I am asking.

I can't find any .380 mag springs that long. Most 9mm mag springs are too wide,

I'll try that, thanks

I understand that Wolf doesn’t list a spring, but I can’t imagine that you’re the only one that has ever wanted new springs. Maybe Wolf customer service has an idea of maybe two springs that could be wired together that would serve the same purpose. I have seen were someone making 50 round Grease Gun mags would use fine copper wire and wire two Grease Gun mag springs together. Stretching the original springs seems like that would be a short term solution to a long term problem. I remember seeing multiple mags welded together. It was so long hanging out of a Mac style registered receiver, it looked more like a walking stick than a mag in a Mac. Good luck with your mag spring replacement project.

[Hey...]

I welded a 50 & 30 z-mag together and 3D printed a coupler for both springs to push against. Looks kinda like a small magazine follower.

If I had a small grip 380 I’d sacrifice one magazine spring cut into 3 or 4 pieces to add 10% to the length of a 30round spring. You’d probably lose 2 - 4 rounds capacity depending on variables but you gain some serious spring pressure.

As a side note, I swapped the 30round Z-mag springs out for PAM-2 springs. Direct swap and much thicker wire with more coils, makes more force pushing against the cartridge stack.

Update
I tried several 9mm mag springs in the .380 small mag well magazines, so far best fit is the springs from 33-rd Glock mags.

UPDATE 2 Wolff sells 33-rd Glock mag springs

I wonder if FTF Industries would sell you some since they sell the whole magazine.

Russell Weeks of GA was making those FTF magazines, but I don't have any contact info. He used to operate under an RPB company name (not the original company)

UPDATE: https://www.rpbindustries.com/
Looks like he he just sells M11/9 parts and mags

Russell usually has a lot more parts than what he has on the website. Most of the time he is hard to get hold of but I'd call or email him and ask.
