I've been trying out some polymer ammo in Kahrs.
I ran 20 rounds of Inceptor ARX ammo through my CT380. Fed and fired as it should and seemed to be accurate to point of aim at six yards. My CT380 cycles Lehigh Xtreme Defense fine so that will remain my carry ammo but I did like the ARX.
Next I bought some Novx ARX 65 grain standard pressure high velocity 9mm. I ran 75 rounds through my CM9 and P9. Very clean, very little felt recoil, and very accurate to point of aim. This ammo seems great except that I had one malfunction with the P9. The slide did not return fully to battery and it looked to me like a round was jammed trying to eject. I dropped the mag and locked the slide back and out of the gun fell an un-fired round with a bullet that somehow broke in half while being chambered. There is no primer strike on the casing and I didn't find the piece of the bullet that broke off. This has absolutely shaken my confidence in polymer ammo. I tried contacting Novx twice via their website but never received a reply.
