Another issue with the 1917

[phenson]

Same one with the rung barrel, I decided to shoot it finally and .45 ACP ammo drops almost all the way through. I thought that only the early Colts had the straight bore cylinders. Has this gun been messed with some more?
Thanks

Someone may have re-chambered it to .45 Colt.

I seem to be asking this a lot lately

Is that safe? If so, I assume I can still shoot .45 ACP safely with moonclips? I already have a 25-5, and I got this gun mainly because of the unavailability of 45 "long" Colt.

If the cylinder has been rechambered to .45 Colt, you should be able to see the "shoulder" where the throat of the .45 Colt case ends.

It is safe to shoot, but accuracy will be poor. This type of conversion to .45 Colt leaves greatly excessive headspace and cartridge positioning will give unreliable ignition.

It's also possible that someone reamed the chambers full length to use with homemaded cylinder length shotshells held in half moon clips. This type of conversion was popular in the 1950s and '60s and was usable even with a "ringed" barrel.

That is exactly what has been done. It is rechambered for 45 Colt.
