So there are some revolvers that are subject to gas cutting the top strap. The one that comes to mind is the 357 Maximum. I understand that the reason for this is that some folks loaded very light, 110 & 125 grain bullets and launched them at huge velocities. The 357 Max was said to be designed to shoot heavier bullets at 357 Mag velocities and if that was done then gas cutting was not a problem.
I have a Russian Nagant revolver. I think most folks here are familiar with the gas seal it uses. The idea was to eliminate all gas escaping from between the cylinder to barrel gap and get an increase in velocity. I saw a test where revolvers with a tight barrel to cylinder gap were tested against single shots and the velocity gain was minimal. So going to the added complexity of the Nagant was pointless...hmm but maybe not.
However, a gas seal like the Nagant's would pretty much eliminate all gas cutting problems.
My ideal pistol would be a Freedom Arms Model 83 chambered for some derivation of 30/454 or perhaps a 357/445. The case would have to span the gap for true gas seal like the Nagant's but you could obtain warp speed velocities and no worries ever of gas cutting....and it would just be incredibly cool.
