Ultra CDP delayed cycling

[Python2]

I am close to 500 rounds in my Ultra. Still suffering in going to full battery and FTF. Had to push slide forward sometimes. Also sometimes experiencing delayed cycling on return to full battery. I can even see the slow moving return of the slide. More FTF using hollow point than ball ammo. I did'nt have any problem with my Pro CDP which is my current carry after so many rounds of break in, but I only use ball ammo.
For all the Kimber carrier, are you using hollow points for your defense ammo? I read somewhere that the 1911 military was designed solely to eat ball ammo nothing else.

Using hollow point, Ranger. Cycles well when it's tested. Practice with CCI Brass, which also works well.

Mine has around 1700-1800 rounds through it now. It still has issues when it gets really dirty. Prices being what they are, I don't practice with JHP, and as a result, I don't carry with JHP at this time either. It's something I need to try at least, but as yet I haven't.

I came back to shooting fairly recently, after 15 years away. My Colts were doing the same thing. I was limp-wristing them. As soon as I gripped them more firmly - pulling back with the weak hand - it went away.

I have had no problems with Federals nor Winchesters semi in my Ultra. I cycle thru the ammo, shooting half a box of the new stuff and the other half is for carry.

I use WWB 230 Grain FMJ or Federal American Eagle 230 Grain FMJ primarily for practice, however, I always finish my practice sessions with Winchester 230 Grain SXT ammunition. The SXT ammo is what I have chosen as my normal carry ammo, and I always shoot up what is in the magazines and replace it with new SXT ammunition when I conclude my practice sessions.

Both of my Kimbers have over 2000 rounds a piece through them with maybe 20% of that being hollowpoints. Other than when I was breaking the CDP in I can not remenber the last time I had a failure to feed or failure to go into battery with either of them.

Thanks,

Bombard may be onto something, but there may be a stronger spring that will help .. just in case the spring is a little off from OEM baseline. Too weak and it may not fully close. Always worth a try ....

Failure to go all the way into battery normally means the lugs on top of the hood are to tight for the slide lugs.

T52 knows all about that.

This is true. I needed to use a little polishing compound and emory cloth to get it to cycle every time. Plus 2000 rounds. Now, no problema!

Python...how's the CDP treating you these days? Did it get fixed? what was the issue?

I also have an Ultra CDP with just over 2000 rounds thru it and I am starting to experience failure to go into battery. It started happening about 400 rounds ago when shot for a 100 rounds and getting dirty. I changed oils, went to more oil, then less oil. Different ammo. Yesterday, it happened right out clean and ready with all different ammo, different mags, etc.

Could this be a lug problem or needing a new recoil spring. I almost purchased the spring online w/ Kimber, but the wife walked in.

If a lug problem, how should I polish the lugs? Or is this a job for someone else?

you need a new spring.

Thanks, I just ordered it. I think the price went up over night.

Anyone use Wolf gun springs in their Kimbers? I've used them in my Hi-power, colts, and sigs without problems.

[X-ffdo]

Ball ammo will do the job just the same!!!! Trust me.
