"Wheel guns" are towed behind vehicles; too big to carry.
I carry and otherwise use several revolvers, so the singular nature of your post puzzles me.
Ruger SP101: I have several of these; the most-often carried has a 2.25" barrel, is chambered in .357 Magnum, and it is presently loaded with 145-grain Silvertip Hollowpoints, a magnum load. This is a back-up gun at work, and can be a back-up or "primary" when on my own time.
S&W Model Model 19: 4" barrel, loaded with the same Silvertips at the moment, but I need to shop for fresh magnum ammo soon, and will see what it likes. This is a new sixgun, and largely untested.
Ruger GP100: I have several of these, mostly 4", but also 3", 5", and 6". The one that I have owned the longest, since 1990 or 1991, has usually been loaded with Federal 125-grain JHPs. As that load seems impossible to find nowadays, I am going to try Gold Dots in various bullet weights.
For the last several years, I have mostly carried the same SIG P229 pistols on my own time that I use at work, on duty. The SIG factory sights have been working well with my aging eyes, until this year, causing me to default back to my revolvers, with which I point shoot better than autopistols. (I did NOT say "hip" shoot; I said "point" shoot; there is a difference!) Getting old is not fun. Of course, I kept carrying my SP101 snubbies through it all, for well over a decade now, regardless of what else I was carrying.
Edited to add: Ah, just realized I had replied to a necro-post.
