Next, try it about 3/4 speed and then try it fairly slow. With a clean and well oiled pistol, insert a unloaded mag into an unloaded pistol and cycle the slide fast, really fast. Start by getting a paint pen and marking your mags with a color and or # to identify them. After replacing the locking block keep the interface areas well oiled as it wears together. You can get lucky and see hairline cracks forming. Also check it during every cleaning and try to replace around 5k or less depending on the power of ammo used. But before we get to the mags do yourself a favor and replace the locking block, before it bites you in the ass by breaking. It is easier to take more, then put some back.I have some experience with this symptom. Do NOT take as much as the Glock has removed. The large frame Glocks had the same problem when they first came out.
To get a visual picture of what I talking about, go to your local gun store and look at the bottom of the slide of a new Glock 21 and you will see what I mean. Taper the area between the factory depth, and the new depth. You should probably take about 10-15 thousandths off, try it, and if you need more, keep removing material until you get it where it needs to be. I can't give you an exact figure, its been too long since I did one. Don't take too much, just enough to cure the problem. Leave the leading edge at the factory depth, then undercut it (raising it away from the cartridge) starting about. The disconnector rail (or what would be the disconnector rail in a 1911), the one that rides over the cartridge in the magazine, needs to be undercut. I also monitor the CZ and the CZ group on if a fix is suggested I'll try to post it here. Funny, these loads worked fine in my old STI Edge & SW 625 (seems I have more guns than sense). 45ACP reloads in the 97 turns out that Montana Gold 200 grn flat points (JSPs) loaded to 1.250 will jam right into the rifleing of a CZ97 and luckily prevent the gun from going into battery while locking it up solid. So far, so good though I nearly got "blowed up" by trying to use some long. It was sold by action arms way back when. 40 cal baby desert eagle - a rare one that has the safety where God & John Browning intended it to be - on the FRAME! and finally a really old copy of the early CZ-75 called an AT84S & made in Solothurn, Switzerland- apparently to get around the difficulty of importing CZs from a then-communist country. the 1911 grip angle - at $250 I could not pass it up), a. 45 ACP CZ-97, a CZ40 (the one that CZ built for Colt w. The gun I am using was loaned to me by a friend & I like it so much that I went a little CZ-crazy buying a.
I have not played around w/ different types of ammo much in the CZ75 I have been shooting in local matches (Tino's, BJ's & our Shooters Paradise match). Sorry for the bad news, at least in my experience.Įrik wrote: "I tried all different types of ammo and couldn't get the problem to go away" If there's a reliable fix to this problem, I might get back into another 75 with you. Try going to his website and see if you can email him your problem or find a topic about this on his forum. The only other resource I would check with eric grauffel. I contacted the factory, they said as long as it doesn't jam, there's nothing wrong. I tried bending the feed lips to pinch the round, nada. I polished the railway under the slide, nothing. I put in Wolff +10% magazine springs, nothing. It happened with 10 & 15 rounders, regardless of manufacture. It didn't do it every time, but enough that it would stick on every other stage. The next round would slide forward in the magazine and the nose would drag against the inside of the frame. 6 months and about another $500 later, I sold it. The small, light weight slide, relativly cheap pre-ban hi-caps, excellent ergonomics, excellent accuracy, reliability, and wonderful triggers if you catch the right gunsmith. The heavy all steel gun shot softer than any other 9mm I ever shot.
In the spring of '02 I bought a CZ-75 DB (decocker model). Ron, Ron, Ron, I wish you had posted this before you bought the 75.
