zymac .380 durability

Postby Don » Wed Nov 29, 2017 7:20 pm

I own a Jimenez and Cobra CA both in .32 acp and like them both very much. Since the .380 pocket craze has taken over I can't seem to find any Jimenez JA .32's or Cobra CA .32's. I've always been leery of these guns chambered in .380 because they don't seem to hold up for long often getting cracked slides. However, I was wondering if they would hold up better with low powered .380 loads. There is some remanufactured ammo that throw the slug at reduced velocities. Do you guys think that the zymac .380's would hold up better with these loads or would they just not feed well or are my concerns about these zymac .380's unfounded?

Yeah, I'm not particularly wild about .380 in my zamak pistolas either. The lack of zamak .32 wunderguns out there ultimately led me to buy the Davis P32 parts gun from Flow (link to thread viewtopic.php?f=26&t=3407 )

Ferg or Jeff Chance: have either of you reloaded lower power .380 rounds?

King's has a Davis P-32 up for auction that might bear watching. But there's no warranty on it since Davis Industries is long gone.

If you're into SNS guns in 32, check out the Cobra FS32. Its huge.

I load .380s with 95gr lead round nose bullets, standard small pistol primers, and minimum or near-minimum charges of powder. I've experimented with #2, Unique, and Titegroup. I don't remember exactly what charges I've used, but most of my guns will work just fine and provide adequate patterns with bare minimum powder charges. Minimum charges usually give a lot less recoil too which will hopefully keep these Zamak wonders last longer.

I have used 2.8 grains of Bullseye under a lead 100 grain bullet in my LCP with perfect results, very comfortable load to shoot. Chronograph velocity is around 790 fps as I remember, which is pretty good for such a short barrel. I would think something like this load would be ideal for the little zamak big bores.

Sorry, 380 isn't a caliber I load for, nor do we own one :oops:

I think the older Jennings m38 is okay. They had a small buffer inside the recoil spring. They lost it later in the Jimenez JA380. My JA was deforming a bit on the frame where the slide contacted it at the back end of the slide travel. I installed a new recoil spring.
my other gun was designed by a russian

its not just the slides that go its also the frames.

if you want a durable 380 zamak you pretty much have to go to the 380 versions of the 9mms out there like the LC380 and that has a bunch of other problems.

I will say the the cobra fs380 is a tough 380 that can take a beating. The even played around with putting it out in 9mm I was told so I think a steady diet of FULL POWER 380acp is fine for those.

the other would be the cobra denalli. Slide is strong. Frame is a very tough polymer (like a stiff zytel). Only weak point might be the zamak barrel housing but I have not heard of a problem yet.

as far as the ja380 or ca380.... stick with the 32 versions and you will be better off. If you do go 380 find some stronger springs and dont shoot them much.

There is also the Hi Point in 380 but it is kinda not good for pocket carry.

I see it done all the time. The tipoff is when you see the pants hanging down below peoples bottoms and they have that funny walk so their pants dont fall down LOL.

Pants hanging half way down your ass doesn't necessarily mean you are packing a Hi Point ;)
There are a lot out there that feel that is a cool fashion statement.
In my day, we used a belt (or a rope).
Have to laugh when one of those tries to run (on the tv cop shows) :lol:
