Revolvers, like any type of weapon, have their limitations. They are bulkier and more difficult to conceal compared to a similar-caliber auto, due to the cylinder. Revolvers lack the ammo capacity of autos. They have lots of openings to admit dirt & mud. In extreme conditions, they are less reliable. This is easy to prove. Take a cigar box with a handful of fine, dry sand in it. Add one revolver, close and shake vigorously. When you try to fire that revolver, the cylinder will freeze up because the cylinder bearing is full of crud. Be advised you'll need to strip down the bearing and clean it in solvent to fix your revolver, probably meaning a visit to the gunsmith. Try this same thing with a Glock or M1911, and the worst thing that will happen is the slide may not return to battery after the first shot. A sharp rap on the back of the slide with the heel of your hand will solve this. Another extreme environment problem is your weapon icing up. If you are in a nice warm room and then go outside into very cold temperatures, condensation will immediatley form on your handgun. If it's really cold outside, it will quickly freeze. It doesn't take much ice to freeze up a revolver cylinder, rendering it useless. The ice on an auto will shatter with the first shot, causing no problems. You can try this for yourself with a spray bottle of water and your freezer. With weakly-crimped ammo (like Glasers, where a strong crimp would crush the fragile bullet), recoil can cause the unfired bullets to move forward in their case and protrude from the front of the cylinder, catching on the frame and jamming the cylinder. These are some of the reasons that military orgs changed from revolvers to autos. Revolvers have their advantages, too. They are dead simple to operate, can be stored loaded & ready to shoot with all springs relaxed, can use low-powered ammo without worrying about functioning, and can handle magnum-level calibers in a less bulky package. The can take odd-shaped bullets (like full wadcutters) without feeding issues. Again, you just need to consider your application, and the strengths and weaknesses of the weapon your considering, and choose accordingly.
