Ammo and Handloading / Re: CZ 97 Barrel "Protrusions"

The problem is the "stoning" job you did likely just sped up what would have worked out just fine after a break in period and down the road could cause a tolerance issue. Time and rounds will bear that out.

Ammo and Handloading / Re: CZ 97 Barrel "Protrusions"
« Last post by Gunzanamo on May 22, 2018, 06:31:49 PM »
Thanks for all the replies.
1. I, too found that shoulder height is critical. That is why I made the new depth plug so that it registers on the shoulder and not on the nose.
2. I, too found that the chamber is tight for length. Rounds that will be "go" in the cartridge gauge will often be a "no go" in the chamber. So I take the barrel off and use that as my depth gauge. Works every time.

3. I also found that the chamber diameter is looser than the gauge. Use the barrel.

4. I found that the shoulder form of the SWC makes a big difference. A radius is much superior to a flat shoulder.

5. Radiusing the "protrusions" was the single biggest improvement to getting the wad cutters to feed. I went from 100% FTF to 25% FTF and then with the radiused bullet shoulders it went to 0% FTF. 

6. So I still maintain that the stoning job is a big improvement. It isn't much material removed. Just enough to remove the sharp edge that the cartridge CASE- not the bullet shoulder caught on.

When I have a moment I'll try to get some pictures on.

Underwhere,
Glad to see you got things worked out, a bit of an eye opening experience to say the least. One thing you showed all of us, was the potential problems you can run into when welding on a casting, pits, inclusions, cracks all can show up in the most unwanted places.. As someone pointed out, now we know why CZ sticks with the polycoat as their default finish...it covers up alot of sins.. I have an example of that on my SP-01 campact, I sent it off to CGW for some work, and part of that was to have the frame, slide barrel  black nitrided, it turned out great! Looking at the right side of the frame however, I found two very small pits on the right side, near the end of the frame, just above the rail.These were on the surface, and had been covered by the polycoat..Myself I don't really care, as you really have to look to find them, the point being, when you strip off the polycoat, you may be suprised at what you find.. This could also explain why for example, stainless guns are hard to get, it could be that getting a frame cast that dosen't have any noticable flaws (pits, cracks, inclusions) may be a little more difficult than we know, after all, the stainless guns are either going to be brushed, or highly polished, so no visable flaws can be tolerated.. I did enjoy watching your journey with this pistol, and can't wait to see the results when it's assembled..

That's a perfect summary and what I believe now as well. Why the Shadow 2 nitride is more expensive than polycoat, why there are so few stainless models etc.
I do hope that they get better with their frames. Perhaps gravity casting or some other methods to reduce the imperfections.

Another option would be to forge the frames, and that would solve all the problems, except that forging isn't cheap, and would add substantially to the manfacturing costs..But the flip side is, you'd have a much higher quality product.. There's no easy way out here..

Agreed.

Note that several CZ models (e.g. P-01, PCR) do have forged frames, but they are aluminum alloy and not steel.

I have a CM9 GEN2 and am looking for a good IWB holster, those look to be OWB. Any other suggestions? Also, mine may end up wearing a small light, so that will be a consideration.

Can't speak for the CM9 Gen 2, but my SAR K2P (CM9 Gen 1) worked great in a Don Hume IWB Holster specified for the 9mm Springfield Armory XDM, and I carried it for three Winters in that Holster just behind my right hip.  That small light won't work with that Holster.

Also, since the SAR CM9 Gen 2 bears quite a resemblance to the MRI Baby Eagle Pistols, Holsters for that Pistol should also fit.

I just looked on the Don Hume site, but didn't see anything listed as specific to the Springfield Armory XDM?

My 97 would take SWC with a shoulder height in a super narrow window to avoid feeding problems when it was new.  This doesn't surprise me.

Picture Link does not work and I've found no reference for such a model.  All  I get is for the Grand Power P40L.

If you could post a pic, that would be much more helpful.

Generally, a good used Tanfoglio Pistol runs in the $300 to $400 USA Dollar Price Range down here. Not sure what the Market is like up in Canada.

Compact CZ 75s / Re: Rattle in my P-01 after loading extra round
« Last post by Gaigebacca on May 22, 2018, 05:16:47 PM »
I noticed the same rattle in my stock 14rd magazine as you did, when carrying +1 loaded in chamber.

I upgraded to these magazines, which come with the hard plastic, low profile flush fitting bases instead of the soft rubber ones from stock, get you another round, and work for both 9mm and .40. So it holds 15 9mm and 11 .40SW, which is awesome. These are great for those of us who own both a P01 and P06, as I do.

I also tried one of these with the +2 base, to get up to 17rd capacity, and it worked flawlessly, and best of all, no more rattle when fully loaded and +1 in chamber!

CZ Polymer Pistols, the new wave / Re: Slide Spyder

Got a set for the VP9, I'm gonna see if they make for the P10.  It really helps, especially with clammy hands.
They do make it for the P10c

Problem solved for now.  TSC had an older model on clearance.  That will work for now and I will keep my eyes open for a "good deal" on a better one.
