Torkk 5 Posted June 9, 2020 So, I had picked up a Kimber raptor 2, and shes been having FTF issues where the round would get stuck nose up in the chamber. I ordered 2 10 round CM mags and they had the same issue. This was using factory and handloads. The OEM mag has the CM shooting star on them, so I assume Chip McCormick makes those mags. I grabbed 2 mags from LGS by work a Remington and Kimber both have different followers when compared to my CM mags I have. I have to try it at the range, but just racking rounds through the 2 new mags, not 1 failure. I tried with the mage that came with the Raptor and the 1st round FTF Are CM mags crap?

WhiskeyTangoFoxtrot 358 Posted June 9, 2020 The old Kimber's definitely had documented issues with their OEM mags scratching/denting the aluminum feed ramps with the follower design so I can easily see FTF issues. I got Wilson Combat 47D mags and never looked back. Quote Share this post Link to post Share on other sites
Bklynracer 1,259 Posted June 9, 2020 Try different ammo. I had issues with 3 mags for my Beretta using PMC, went back to federal not one issue with any mag. Quote Share this post Link to post Share on other sites
Shocker 150 Posted June 10, 2020 Is your problematic ammo round nose? I had a Springfield that would give me issues with anything but round nose - no matter Cobra, Wilson or Springfield mags. It went back to Springfield who tried polishing the ramp and tuning the extractor but I’d still get a 3-point jam maybe 1 in 100 rounds. Quote Share this post Link to post Share on other sites
beachwhistle 28 Posted June 10, 2020 Cobra mags worked well with my Kimber. Quote Share this post Link to post Share on other sites
JC_68Westy 1,024 Posted June 11, 2020 I have a Kimber Stainless Pro Raptor II and had issues when I first got it when shooting ammo loaded with lead bullets. The lead ammo was out of spec. It ran in my other 45 ACP guns but hung up with the out of spec ammo. The ammo was too tight to fit in the chamber easily. I ran the ammo through the crimp die in my press and the problems disappeared. I tried all of the good 1911 mags. The gun shoot with any mag/ammo combination as long as the ammo is in spec. I can also say that the gun became really reliable after a few hundred rounds. It hasn't hiccuped at all. Quote Share this post Link to post Share on other sites
Handyman 5,682 Posted June 14, 2020 I've used the OEM supplied mags and Wilson Combat with no problems. Quote Share this post Link to post Share on other sites
Torkk 5 Posted June 14, 2020 I recently picked up 1 Remington 7 round and Kimber blued 7 round with the dimple on the follower. Those worked well initially with my SWC handloads, and the my OEM kimber CM mag failed. It was weird, the rounds that failed to load ended up chambering fine and firing later in my range session. I ran 100 rounds of factory and 1 think around 30 rounds of handloads, and what failed at 1 point fed well at a later point. I did remove some tension from the extractor, and noticed no abrasions on the rims of the casings after firing. I thin the tension was too high before, I just have to get more range time with her. I'll be loading some FMJ RN later this week and check those, but I'll be trimming to spec and yadda yaddda Quote Share this post Link to post Share on other sites

The ammo I had to re-crimp all passed the Lyman ammo checker test and was still too tight for the Kimber chamber. I haven't had an issue since I adjusted the taper crimp die setting. It was very frustrating until I figured it out. Quote Share this post Link to post Share on other sites
