Femaru 37M recoil Springs: differences?

Hello All,

I have found the recoil spring and firing pin springs for the Femaru 37M for sale in a few places, not least of which is by Wolff Gun Spring company.

What concerns/confuses me is that there is no distinction being made regarding different springs for different calibers.

It also seems there may be more .32acp Femaru 37M than .380acp Femaru 37M.

I have the .380, of course, and all of the spring sets I see are either unstated for caliber or are listed for the .32.


SO, is there a source for .380acp Femaru recoil springs? or is there no difference between the .32 and .380 recoil spring in Femaru 37M handguns?


Thanks in advance [oh, and if anyone has a .32 barrel that they don't want any longer, contact me].
