The problem with the
bold yellow statement above is that blanket statements like that are just not accurate. The problem with the
bold red statement above is that it is very subjective.
The bold yellow statement really depends what you are comparing it to. A 25 oz Llama .380 to a 39 oz Browning Hi Power 9mm? Sure, there might be some validity there. But beyond that the argument starts to fall apart. I've shot the Llama .380 and it's typical of a 25 oz blowback .380 ACP like the RIA Baby Rock or blowback operated .380 ACP pistols like the PPK/S, FEG AP9S or APK9S weighing 27 to 28 oz.
It's subjective, but I personally don't find any of them particularly difficult or uncomfortable to shoot and 100 round range sessions don't make my hand hurt. Let's use that subjective impression as a start point for an objective discussion and comparison of weight and recoil.
The alloy frame FEG SMC .380 is much lighter at 20 oz loaded, and being a blowback design the recoil is much sharper feeling than a PPK/S or Baby Rock. However the grip is also reasonably wide and again I don't find it uncomfortable to shoot - although it is admittedly my least favorite .380 ACP to shoot.
The Kimber Micro and Sig 238 are .380 ACP pistols weighing right around 17 oz loaded. However, they use a delayed recoil locking system like the 1911, so while the recoil is technically slightly more than the 20 oz SMC, it's spread over a bit longer period of time and it feels very much like the 27 oz PPK/S and 25 oz Baby Rock pistols.
In contrast, the Kimber Micro 9 and the Sig 938 are not much larger than their .380 counterparts and weigh about 21 oz loaded. However, they produce a lot more recoil due to the higher velocity and heavier bullet commensurate with the 9mm Luger cartridge. Neither of those are my first choice to fire in a 100 round range session.
I do however carry a CZ 2075 RAMi from time to time with the short 10 round magazine installed. It weighs 30 oz loaded and it is both comfortable and controllable to shoot. It's as small as I like to go with a 9mm Luger pistol as below this threshold controllability starts to suffer and they become uncomfortable to shoot, which means you won't practice enough with one to get really good with it.
Whether you are shooting a 9mm or a .380 ACP, the thing to keep in mind is that neither one is effective when you miss. If you miss more with a sub compact 9mm Luger than you do with a compact .380 ACP, I'll argue the .380 ACP is a much better choice for you.

Let's look at some comparative recoil numbers and let's start with the 17 oz Kimber Micro with it's delayed recoil locking system using a 90 gr bullet at 910 fps:
Kimber Micro (17 oz, 90 gr 910 fps)
Recoil Impulse = 0.45 (lbs.sec)
Recoil Velocity = 14.27 (fps)
Recoil Energy = 3.23(ft.lbf)
Next let's look at the 20 oz blowback operated SMC with the same load. This is where the numbers are a bit deceptive as the operating systems are not the same. While the numbers are lower for the SMC, the "felt" recoil is subjectively better in Kimber Micro as the delayed recoil system spreads the recoil out over a longer period of time:
FEG SMC (20 oz, 90 gr 910 fps)
Recoil Impulse = 0.45 (lbs.sec)
Recoil Velocity = 11.65 (fps)
Recoil Energy = 2.63 (ft.lbf)
Now let's look at the 25 oz Baby Rock with the same 90 grain load at the same 910 fps velocity. You'll note the recoil impulse is identical so far in all three examples (same bullet weight and velocity), but the increasingly heavier weight of the pistols reduces the recoil velocity and recoil energy:
RIA Baby Rock (25 oz, 90 gr, 910 fps)
Recoil Impulse = 0.45 (lbs.sec)
Recoil Velocity = 9.33 (fps)
Recoil Energy = 2.11 (ft.lbf)
However, the Baby Rock has a 3.9" barrel rather than a 2.75" barrel so realistically it's going to launch a 90 gr bullet at around 1050 fps. That bumps up the recoil impulse and in turn the other numbers. It's now very similar to the SMC in terms of recoil, but with 140 fps more velocity and better terminal effectiveness:
RIA Baby Rock (25 oz, 90 gr, 1050 fps)
Recoil Impulse = 0.51 (lbs.sec)
Recoil Velocity = 10.49 (fps)
Recoil Energy = 2.67 (ft.lbf)
The 27 ounce PPK/S has a 3.5" barrel and will launch a 90 gr bullet at around 1000 fps with slightly less recoil impulse than the Baby Rock but more than the SMC:
PPK/S (27 oz, 90 gr 1000 fps)
Recoil Impulse = 0.49 (lbs.sec)
Recoil Velocity = 9.35 (fps)
Recoil Energy = 2.28 (ft.lbf)
----
For comparison purposes with the delayed blowback 17 oz Kimber Micro .380, let's look at the delayed blowback 21 oz Kimber Micro 9 using a 115 gr bullet at 1050 fps to reflect the short 3.15" barrel length. You'll note the much higher recoil impulse and the much higher recoil energy in what is very much an apples to apples operating system comparison:
Kimber Micro .380 (17 oz, 90 gr 910 fps)
Recoil Impulse = 0.45 (lbs.sec)
Recoil Velocity = 14.27 (fps)
Recoil Energy = 3.23(ft.lbf)
Kimber Micro 9 (21 oz, 115 gr at 1050 fps)
Recoil Impulse = 0.65 (lbs.sec)
Recoil Velocity = 15.89 (fps)
Recoil Energy = 5.14 (ft.lbf)
----
Now let's get to the heart of the issue and compare the Micro 9 to the 30 oz CZ 2075 It has a 3" barrel but we'll use the same 1050 fps. We'll also use the Kimber Micro .380 in the comparison. Note the same recoil impulse for the CZ and the Micro 9 (same load), but also note the much lower recoil velocity and recoil energy numbers for the heavier CZ 2075:
Kimber Micro .380 (17 oz, 90 gr 910 fps)
Recoil Impulse = 0.45 (lbs.sec)
Recoil Velocity = 14.27 (fps)
Recoil Energy = 3.23(ft.lbf)
Kimber Micro 9 (21 oz, 115 gr at 1050 fps)
Recoil Impulse = 0.65 (lbs.sec)
Recoil Velocity = 15.89 (fps)
Recoil Energy = 5.14 (ft.lbf)
CZ 2075 RAMI (30 oz, 115 gr at 1050 fps)
Recoil Impulse = 0.65 (lbs.sec)
Recoil Velocity = 11.1 (fps)
Recoil Energy = 3.59 (ft.lbf)
You'll also note the recoil velocity of the 30 oz CZ 2075 is actually lower than the 17 oz Kimber Micro .380 ACP and the recoil energy isn't significantly higher. In fact, if you shot them both you'd agree the recoil is pretty comparable. Your main observation would probably be that the larger grip on double column magazine CZ spreads that recoil out a bit more on your hand.
Last, just to round it out, let's take the large frame BHP weighing 39 oz and see how it compares. Since it has a 4.625" barrel we'll give it a full 1150 fps velocity. You'll note the higher recoil impulse due to the higher muzzle velocity, but note the recoil energy of 3.23 ft.lbf is exactly the same as the Kimber Micro .380 ACP. The difference is the much lighter Kimber Micro has about 50% more recoil velocity, so it's recoil feels sharper than the BHP:
Browning Hi Power (39 oz 115 gr, 1150 fps)
Recoil Impulse = 0.7 (lbs.sec)
Recoil Velocity = 9.24 (fps)
Recoil Energy = 3.23 (ft.lbf)
-----
The cliff notes version of all of the above is that you've got two pistols here with very similar recoil - a Kimber Micro in .380 ACP and a CZ 2075 in 9mm Luger. However, the Kimber Micro only weighs about half as much as the CZ 2075, and it is significantly thinner. The Kimber Micro makes a good pocket pistol, while the CZ 2075 doesn't. On the other hand, the CZ 2075 is still compact for IWB carry and offers 10+1 capacity with 9mm Luger capability.
