When toting revolvers, I really like the Milt Sparks PMK for the smaller to medium-large weapons, up to K/L-frame/GP100 size. The Milt Sparks 200AW is really nice, too, but its long tunnel loop is not compatible with all belt loop spacing, and the hammer shroud is not needed for my revolvers that have no hammer spurs, or smaller-sized hammer spurs.
I have yet to settle upon a current favorite for larger revolvers, as I do not tote them regularly enough, anymore. The Sparks Hackathorn seems quite good, outside the belt, and the Summer Special works well IWB, with a 5.5"-barreled SAA. I used a Davis DA Challenger to carry my S&W Model 58, but finally realized my hands were simply not quite large enough for the N-Frame.
I like the Alessi Ankle Holster. I do not routinely use ankle carry, anymore, but it is a viable method when long pants are worn, but belt-level carry is going to be problem, for whatever reason, or, of course, for a secondary weapon.
I live in a often-tropical climate, unsuited to shoulder carry for most of the year. When the temperature allows suitable cover garments, the Andrews Monarch is a very well-thought-out shoulder rig. The added strap, that crosses the back, below the shoulders, makes tie-downs unnecessary.
The Josh Bulman FDS (forward-drop scabbard) is superb, for my 1911. Notably, it is much like the Sparks PMK. Both are evolutions of the Professional, designed and made by the late, great Bruce Nelson. (A more-faithful copy of the original Professional is the Milt Sparks BN-55, with "BN" being, of course, Bruce Nelson's initials.) When I toted P229, its natural habitat was also a Bulman FDS.
The Kramer Vertical Scabbard works well with several of my handguns, both auto and revolver. The concept is, again, a development of the Professional. Another Kramer I like is the MSP Paddle Holster, for the relatively few times I want to use such a holster.
Having mostly switched to Glocks, for duty and most personal-time carry, due to aging, aching hands, wrists, arms, and a bad shoulder*, I have also tended to use kydex and other thermoformed holsters. The best of the best, outisde the belt, that I have found, thus far, is the DSG Arms Alpha, accomodating the pistol, plus a mounted X200/X300 weapon-light. I also like the Raven Concealment ACR, for a G26, worn IWB, forward of the hip, a.k.a. AIWB. (AIWB is a controversial carry position, especially for weapons having a short trigger stroke distance, so I do not recommend it. Those who truly trust themselves to stay off the trigger, until the target is acquired, know who they are, and can make an informed decision.)
*9mm recoil is kinder to aging joints, and the low bore axis of Glocks reduces muzzle flip. An X300/X200 weapon-mounted light adds recoil-damping mass at just the right place on the weapon.
