@thendrix Get a good 22lr and a 12ga too. It might seem dumb but they are good against most problems. 9mm, 10mm and 45acp are only good enough to buy time to grab a long rifle.

Looking back into the history of 38spl shows that it was improved to be good enough until semi automatic pistols became more common. To replace the old work horse the police looked at the 1911A1 because it was developed to take down a horse. The recoil is just enough to let one know they don't have a squib and it has the penetration of a limp dick. 9mm was... double stack and suited for people who don't get yelled at for not managing recoil.

10mm, the real one and not 40S&W, was so impressive that the FBI had to lower their standards for qualifying. The barrels were wearing out before 10k rounds. It's the round that would get your grandpa to say he never truly enjoyed his 45 except for killing Germans. The recoil can be around the same between a 10mm and a 45ACP. One goes faster, penetrates and is Metric. The other is old, dead simple to handload and so heavy that the effective range is two distances. The one it easily reaches and the 9.81ms^2 that forms a parabolic arc into death from above.

To summarize, a revolver is hilariously inefficient at utilizing the gasses from a round so much so that its escape will eventually cut the frame and cause catastrophic failure. Reloads are terrible with revolvers. Just get something semi automatic and enjoy the century old luxury of something called a magazine. There's also the benefit of using a suppressor and rails. 9mm, 10mm or the Ancient round that has limp dick penetration but hits like a haymaker. They all have their unique uses and the argument could be made to just have all 3.
