Range Report

[rmw1]

Fired my new CZ40B for the first time today.
100 rounds of Win. white box 165 FMJ.
On the 7th round, the slide went to slide lock with 3 more round in the mag. No apparent reason that I could see. I dropped the slide and kept firing. Functioning was perfect for the next 93 rounds.
The recoil was a little more than I expected. I realize it's got an aluminum frame, but the gun is not particularly light. The forty is definitely a snappy cartridge. My Browning .40 is a bleepcat in comparason. Even my Sig 245 recoils less with ball ammo.
The funny thing is, I took my S&W 66 Hi-Viz and shot the 125gr. gold dots. When I went back to the CZ, the recoil was nothing. All relative I guess.
Other than the front site being off center and it consistantly shooting 4-5 in. to the right, it was a good buy... but...
in retrospect, I did not get this one for defense or CCW. I have a 75B in 9 that I love, and should have got another, just for plinking and enjoyment considering the difference in ammo prices.
Now I have to decide between the S.A. or the compact next. leaning towards the compact...   r

Well it sounds like you are well advanced in a serious case of CZ-itis. Either the Compact or SA would make a great choice for your next one. You can't go wrong.

[Walt-Sherrill]

I'm not sure the frame is aluminum.  

CZ calls it an ALLOY frame, but doesn't mention which metals make up that combination.  

Its lighter than other frames, but not as light as some aluminum frames I've handled.

[rmw1]

interesting point concerning the "alloy". all i know is that it is not at all magnetic, using a strong magnet.
i would be interested if anyone has more info on this.

Which prob means why we have not seen any cracked frames. like one would with
some alum frames.

The Z40 alloy frame was a rapid departure from CZ's age old steel frame.
Maybe when the 40B has 2 or 3 years of field use..they will show some
frame wear and cracks.but i doubt it.

Designedaroun the 180 gr police ammo of that time. The Z40 and now 40B
seems pretty rugged. It's a lot of gun for $300 or so Dealer price.

Walt, you have looked inside one. Tell me if you think it can be made for SA
only?

I don't really care.as i have the SA's i want. i just think Somehthing could be done
to make the 40B's trigger pull better.

I've give some serious thought to NP3 or some teflon coating of the entire gun & parts, if i
was a 40Bophile.

[Walt-Sherrill]

I've looked inside them, but didn't do any measuring -- so can't really guess about whether they could be made SA, or not.  But the bulk of the parts appear to be identical.  (With a loupe or a micrometer, you might see something different.)A

As a layman, I'd guess the parts are generally interchangeable.  But that's only a guess.

(You get kind of carried away with the enter key, sometimes, don't you?)

[JUNGLE MAN MOD]

I got em taken care of Walt. For a minute I thought that I wasn't awake yet until you mentioned it too.

[MILLERCHRIS]

Today I went to the range. loaded "both" my mags and placed the targets at 25 yards.  I shot at my top target then I grabbed the other mag and started to shot it. When i got my targets I saw that the top one had great groups of 2/3 inches about 1 inch low. The other target I was all over the paper mostly high if I hit it at all. So I placed two more targets out and again same thing.
 So I put my targets out at 10 yard loaded the mags shot 10 rounds at each target. One target was all in the ten ring the other one was high and to the left 2 inches with a couple flyers that were all over.
 Now I have been unhappy with the way this gun has shot since I got it. I have blamed the gun the ammo and myself. Seems that the gun hasn't been the problem but it been the mag the bottom of the mag doesn't sit right its loose. The other problem has been cheap ammo.
 I have been only using  one mag with the gun when I have gone to the range. I have never heard that a mag could cause accuracy problem. Could the mag have cause this to happen?? I shot only UMC a Win-Clean ammo and both shot very well . I was so happy that I found the problem that I went and bought another box of ammo from the range "BIG MISTAKE" it was Winchester white box ammo it failed to feed about every other round. but other then that I'm very pleased. the trigger still needs work though..

[Walt-Sherrill]

I don't really undestand how a mag can affect accuracy, 'cause when the slide is closed and a round is chambered -- the point where  you're ready to pull the trigger -- the mag is out of the loop.

It's got (at least as far as my somewhat limited knowledge is concerned) to be something else...

Try the same shooting drill from a bench rest (a table, etc.).  I think you'll find that with slow fire, the accuracy will be the same.  If so, its most likely "technique."

And, yeah -- White Box is a real problem for some guns.  I avoid it.

Moving this to review section/

[MILLERCHRIS]

No it was the same slow fire / from the bench didn't seem to matter? I'm thinking that the mag might be letting the bullet get damged. Either in the mag or while being cycled . I think this is mostly the problem. I have targets and a friend that was with me to prove the differance between the mags.
 I have to agree with you about the mag not being the problem but I know that there is a differance.

[ut83]

Strange situation.  Check the difference in the brass between the two mags.  I dont know what you will be looking for but it may tell you something..who knows?  Theoretically, Walt is correct..the mag shouldnt have anything to do with accuracy.
The mag shouldnt contact the bullet in anyway that would damage it.  Curious at least.
Shoot well
