Yep, in theory it "should" work. I'm just curious how well it works in practice. Unfortunately it's hard to test unless you've owned one and swapped cylinders back and forth to see if it's still reliable and accurate.
Most of the time if I'm curious about a gun I'll go rent one to try it out, but this is the kind of thing you can't test with a rented gun.
I would guess having a swappable cylinder effect accuracy compared to a none removable cylinder. However it's probably not much to notice. Why 9mm? 38 Special isnt that much more. Get a 357 and just shoo the cheaper 38.
Why 9mm?
Efficiency. I have lost in a tragic boating accident several other 9mm handguns. If I want to visit the range on a whim, I can just grab my range bag and be confident that there are a couple hundred rounds of 9mm FMJ in it for plinking.
If I buy a non-swappable .357 Mag, I'll need to start keeping .38 Special on hand for just that gun. Also, .38 Special ammo is twice the cost of 9mm so it's more ammo to store and more money.
Additionally, if the SHTF, I'd rather have guns that use the ammo I have cases of than be some tacticool idiot with 15 guns that are a single box of ammo away from being a paperweight.
My SHTF gun is a 12ga single-shot break barrel. There is a company that makes adaptors for any caliber. IE I could shoot 22lr, 9mm, 38special, 20ga, 410 etc etc. In a 8in the barreled adaptor. They even have a reloadable black powder adaptor. With one gun and the adaptors, you can use any ammo.
