Most pistols are so easy to field strip I can't imagine why one wouldn't clean them after each trip to the range. If it's a gun you're not familiar with, and fear the take down procedure, there are videos posted on You Tube showing visual disassembly and reassembly of most every type and model.
I consider cleaning after shooting a weapon every bit as important as shooting with it. Revolvers are even easier because they require no disassembly what so ever. Keeping the cylinder face and forcing cone free from buildup will assure a good running weapon. Again this is so easy to accomplish I can't imagine not doing it.
There are a few guns I will not break down because they are a PITA to reassemble. The Ruger Mark II and Mark III .22 auto pistols are the best examples I can come up with. With mine I just give them a good "washing" with clean Kerosene or WD-40 with a stiff bristled paint brush, (It won't hurt wooden grips or any plastic), then blow completely dry with compressed air. You won't believe the crap that will wash out of that pistol after several hundred rounds. I do much the same with magazines rather than disassemble them. After that I relube everything and it's good to go into the safe until the next range session.
