Swap Cylinder model 10?

[WestKentucky]

It’s not incredibly difficult to pull a yoke on a model 10, and parts are fairly cheap and easy to get so I’m wondering if it might make sense to do a swappable cylinder assembly in 9mm and possibly even in .357. I might even consider one in .380acp. Has anybody done a swap assembly? I know timing will likely be the biggest issue, especially maintaining timing for 2 or more cylinders.

It would be a lot of work and hand fitting to get multiple cylinders to fit one gun. Also not a good idea to step up in pressure ranges, a mod 10 from 38 spec to 357 would work but the pressures would quickly stretch the frame.

9mm would be cool but I also think 357 would be hard on the gun

9mm is up around 357 pressure. Both around 35,000 psi.

Didn’t Jim Cirllo of NYPD stakeout squad fame run a Model 10 with a Model 19 cylinder? Seems to me heat treating of the frames would be the same.

The forcing cone would likely have to filed down to accommodate the 357 cylinder and by doing so the 38 cylinder would no longer work with the gun. I reamed the cylinder on my model 10 to accept 357. I’m not saying you can do it, only that I did it.
