My wife is a proficient shooter. Expert ribbons in both pistol and rifle from her Navy service. Owns a Beretta 92 as her home defense choice since she carried one (yes, carried) when she was deployed. She has relatively small hands. She can handle the Beretta well. Shoots better than most people at the range when she goes.
When she wanted a concealed carry pistol, we went to the range, and she tried the S&W Shield, the Glock 43, and the Walther CCP. All 9mm single stack. All quite concealable. My preference was the G43, based on my perception of reliability and commonality with other Glocks I own.
She found the recoil on both the S&W and the Glock to be objectionable. Despite being an experienced and capable shooter.
One round through that Walther, and she looked at me and said, “This one!”
It’s difficult to quantify recoil, because some of the perception has to do with how strong the shooter is, and how the gun fits their hand, but in shooting her CCP, I would put the recoil reduction over the Glock and S&W in the 30-40% category. It’s that good.
In comparing a Glock 42 (a .380 of comparable size) and the CCP in 9mm, the Walther has significantly lower recoil.
The gas piston recoil management really is a remarkably effective system.
So, once again, I’ll strongly encourage you to try the CCP.
