Hi,

I'm starting to see lots of stovepipes in my SP01 (empty brass getting caught in the slide)... I like the heavy (factory) recoil spring, what's better for addressing stovepipes - lighter recoil spring or stronger extractor spring? today i also had a situation where empty brass didn't get pulled out of the chamber...

Thanks!
 
yeah, that's not really an option, plus these are loads which never gave me any problems in the past...
 
In that case a lighter recoil spring is the route I would go. But if using lighter recoil spring on your CZ, I would buy and install a recoil buffer. For 12 bucks shipped it may save your slidestop..

I don't own one, but this makes me think that the problem may be with the extractor. If it isn't gripping the case properly to extract it, you would get this, and stovepipes when it released the case before contacting the ejector properly. I'd get that checked, since the issue may not be spring-related at all.

Yes, get rid of that heavy-ass factory 18# recoil spring and install a standard CZ 14# spring. No recoil buffer needed.

Tell it to the folks who broke their slidestop..
A few dollars are not a big investment.

Gee, I dunno. I just talk to the guys who put thousands & thousands of rounds through their CZ's and don't break anything, mine included. Given the number of CZ's out there, slide stop breakage is very uncommon. The SP-01 is just a variant of the CZ75B. The standard weight recoil spring on the 9mm CZ is 14#. Many people use 11# and 12# springs in their pistols with reduced power loads. Why the manufacture used a 18# recoil spring in the SP-01 is anyone's guess. Maybe to make sure dirty, crappy ammo chambers? using +P+ ammo? Bottom line is, the 18# spring is too heavy and can contribute to slide stop breakage by slamming the slide forward. If you think the 14# spring is too light, put in a 16# spring and go with that.

if the load worked before and and now isn't reliable it's NOT the recoil spring; if anything it gotten ligher with use... it's likely the extractor...
 
if it's a cz-spo1 with the original recoil spring,it's definitely the spring,just like Gunnar said,and just like every other one that I know of when trying to shoot lighter loads instead of the higher power service loads the gun was designed for,mine included.
 
Just a thought, but you may have some gunk in there that you didn't have before... may be slowing things down? You probably already have done so, but try a thourough cleaning... incl extractor.

I would second a good cleaning before I got too worried.

The SP-01 I had digested all but 1 round in the 1200 or so I put through it.

Almost perfect.

Most of the ammo I shot was Canadian BDX which is factory reloaded ammo.
 
Are either of your thumbs coming in contact with your slide. I had a 1911 that started to stove pipe every now and then. It was me not the gun, I slowly slipped into a bad habit after years of shooting and I thought it was the gun.

Check your technique first.
 
well, I'm not so much worried about my own performance (touching the slide, etc), I do clean the extractor on a regular basis on this gun, and the thing with the springs I agree that a spring gets weaker over time, not stronger, so that might contribute to the slide stop breaking, but not to stove pipes. I put a stronger extractor spring in there, and still had issues...

So I'm switching to Combat Masters ammo for matches now, and I'll use up the winchester in practice. Too bad, since I like the recoil characteristics of the win ammo slightly better, but it's a 1-2% thing, whereas a single stovepipe in a match costs me much more than I gain from using win ammo...

Thanks!
