Accuracy of SP-01 vs 75B

[tvphotog]

Can someone please compare the accuracy of the SP-01 to the 75B? I'm looking to buy one or the other.

Out of a rest, not much, if any.  The SP01 allows you to get a slightly higher grip.  Combined with the added weight, it allows you to squeeze as much accuracy out of the platform as you can (ala SP01 shadow target, etc.), especially for quick follow up shots.  If you are looking for the highest possible grip, SP01 or SA is the way to go.

For a field or range gun, both can be tuned to have excellent accuracy.

What is going to be the use of the pistol?

^^ This ^^

If you are going to be doing traditional Bullseye style target shooting, you wouldn't notice a lick of accuracy difference between the two.  HOWEVER, if you were looking to shoot an action sport such as USPSA, IDPA, 3-Gun, Steel Challenge, etc, then the SP-01 would be the better choice due to it being more muzzle heavy.  The heavier muzzle of the SP01 allows it to shoot flatter for secondary follow-up shots.

For the range. I'm not going to do competitions, but I love a one or two inch group at the range now and then. For home defense, I'm a bit concerned about the difference in trigger weight between decocked and SA, so now I'm using the P30 at home with an LEM light DA pull each time.

Either would suite you fine.  You can get either model with a safety or a decocker.  You just have to pick the style you want.......rail or no rail........

Because I may smooth out and reduce the weight of the trigger pulls in DA and SA, I might want to use this as a home defense gun as well as for range use. I've ordered the SP-01 because I want the rail for a light.

Sounds like you made a great choice!  I don't think you'll be disappointed.

 Interesting post. I have a 2015 production 75 B and a 2016 production SP-01 Shadow Target II, both bought new and unmodified. Bench rested, my 75 B is actually more accurate with all but a few loads. That may change some as the SP-01 is shot more, but the few loads that are more accurate than the 75 B are very accurate indeed. The 75 B is pretty accurate with nearly any 9mm load and the SP-01 can show a surprisingly loose group with mainly lighter loads.

 Shooting off-hand, my SP-01 Shadow will group tighter for me, and allow a faster rate of fire doing it. I had both guns at the range today, trying some plated bullets. Rainier 124 HP's at 1.090" OAL with 5.4gr of Power Pistol were amazingly accurate in the Shadow, and almost as good in the 75 B.

 The 75 B was my first CZ. Its overall performance got me into buying more CZ's. A recently bought P-09 is showing great promise and I think it may be a sleeper for rested accuracy.

My 9mm  75B and 75 Shadow are very much the same gun for accuracy.  The heavier bbl and front end of the Shadow make shooting them a little different depending if it's slow fire, fast multiple shots on one target or multiple targets.  Off a rest,  they are both better than the shooter, so hard to say which is most accurate.

As long as the lock-up is consistent, and it is with 75 series, the accuracy should be essentially the same. 

What is missing from discussions about the accuracy potential of the CZ design is barrel dwell time.  CZ's have excellent dwell and this is a significant contributor to their accuracy.

I don't know what this is.

Schmeky,
You opened a can-o-worms....
I am familiar with Dwell time and it's affect on recoil and cycling reliability in Gas impingement and piston systems of semi auto rifles.
How is this manipulated in a CZ SP01 for example?

I just shot my stainless Limited 9mm, SP-01 9mm, and a friends Tristar S120 9mm back to back, 10 rounds from each.

At 10 yards, all three guns shot (for me) about 1" groups, with the Limited and the S120 grouping just over 1", and the SP-01 grouping right at 1".

The only difference is that the SP-01 is easier to shoot faster.

Not a can of worms at all.

Dwell in a semi-auto Browning style firearm is how long the barrel will stay in the exact plane once the slide begins moving rearward.  The slide will move rearward, as will the barrel, before the projectile exits the muzzle.  So it's critical the barrel stay in it's plane with no vertical or lateral movement as the bullet leaves the end of the muzzle. 

Good dwell, like in a 1911 with a good, properly machined and match fitted parallel set of lower lugs, coupled with a match fit bushing, is a prime example.
