SP-01 Break In...

[ScottJ99]

After much reasearch, I made the decision and bought a SP-01 from CZ Custom.  I received it Tuesday and proceeded to put 100 rounds down range.  Here is my question/Concern:

I had approx. 7-8 stovepipes in the first 100 rounds.  I realize there is a break in period, but at what point should I consider the gun broken in?  At that point, what do I need to do to eliminate the FTE's.  I am pretty sure I did not limp wrist any of the shots.  Any advice would be greatly aprreciated.

I usually shoot about 500rnds looking for issues..
usually I'll run a gun in competition or carry if I get 300-400 rounds trouble free.

what ammo are you shooting?? FTE-eject? or extract?

I have had a few failures to feed in my first few hundred rounds with my SP-01 tactical.  All of them have been with the same type of ammo so I am hoping that is the only issue.  If it is a consistent problem, I am going to be very concerned.

I have an SP-01 Tactical and am still breaking it in. Also with some failure to feed problems but I will stick through the break in period and see what happens.

Interesting that you have had problems as well.  I really hope that this is not a significant reliability issue.  I know there is a sticky about things you can do to minimize problems with the SP-01 but I have a hard time buying the idea that I should have to modify a brand new gun to make it reliable.  If this continues, I am unfortunately going to have to seriously consider buying something else.

Don't worry, my shadow had a handful of FTFs and stovepipes in the first 300 rounds. Since then I haven't had a stovepipe or FTF in the next 1000 rounds. I polished the feed ramp with 000 steelwool and that cured the FTF.

eerw,

I used 115gr. FMJ (American Eagle? - not sure of the brand).  Not sure what the difference between eject and extract is,  I would guess eject, the failures were stovepipes, as a result of the spent casing not ejecting, the next round would not feed properly.

[Stuart]

I have run the AE115s with good results..
stovepipes would be a failure to eject. if the case was being left in the chamber and the extractor not grabbing it, that would be a failure to extract.

since a stovepipe you recoil spring may be too heavy or just need to take a set.

eerw,

Thanks for the info.  I think I will continue to monitor for 300-400 more rounds, if I still have a problem, I will change out the recoil spring for a lighter one.  What do you recommend?  I will be using for target practice, HD as a secondary purpose, and maybe further down the road some IDPA.

I run 11# spring in my CZs for my USPSA/IDPA loads and factory ammo. I run a 12# or 14# spring for +P ammo

All info is appreciated. This is not my first SP-01. I need to run more ammo through it. Not enough break- in time. Also shot the SP-01 as soon as I got it. Really needs to go to the range after a good cleaning.

Thanks.

I'd never shoot a CZ pistol without taking it completely apart for a thorough cleaning. They cake those suckers with so much grease that once hot powder hits them it seazes like crazy.

Those stovepipes must be very frustrating. Scott does not appear to be the only one whose SP-01 has teething problems.

I wonder if perhaps CZ's spring supplier(s) has trouble making recoil springs of consistent "weight" ?

[pitbull]

I know I should have cleaned it first, but I was anxious to try it out. Not the best choice in hind sight.
