I owned and occasionally carried a CZ-75 9 mm in the 90s, with only 12 rounds in the magazine and one up the chamber, as I noted the magazine spring set considerably over time.
I then also occasionally carried a Browning 7.65 mm, but this time in the pocket, because it was too small for belt carry. It was not big but it felt very heavy, even in a coat pocket.
A revolver would be much worse to carry, because the cylinder fattens it: I have never owned revolvers so I don't claim to know, but they are worse for inside-the-waistband carry than pistols for sure.
The CZ-75 is all steel but, considerably slimmer than the Glocks, and most others that are the rage these days. I did try a holster and it only worsened its bulk: In the end what I used to make it easier to take was a bit of foam padding, which also kept the sweat away (though being thicly painted in black enamel, it didn't rust).
I never stopped feeling utterly ridiculous carrying this artillery around. I could never forget for a minute I was carrying it, while Lile's "Mission" is like a long feather you can't help forgetting you have it...
So even having the experience with only all steel guns, I doubt lighter guns would be any better.

P.S. Biggest hassle with the CZ-75 was the entire plastic "handle scales" were each held by one single screw, and had to be replaced with more rigid wood panels, fortunately those were offered as an option even back then.
