Glock 9-40 Convert

[Evan632]

I know you can convert the .40 to 9mm, but can you convert the 9mm to .40?

I would guess no, b/c of the outside barrel diameter. I did a quick check over at Lone Wolf and did not see a barrel for 9mm --> 40.

BearIT is correct.

The 9mm Glock's are not able to accept larger barrels. This is why it's better to buy the .40SW models. With that platform your Glock is capable of shooting three calibers, 9mm - 40SW & .357Sig.

You'll need to buy 9mm magazines along with the 40-9 conversion barrel using a 40 caliber Glock. But going to .357Sig only the conversion barrel is necessary because the 40 magazines will accept the .357Sig cartridge.

Correct, the OD of the .40 barrel is .020 larger than the OD of the 9mm barrel.

This. And the Lone Wolf barrels work great in my Glock 22....Never had any issues.

I always think of the Glock as convertable to a smaller caliber but not a larger. The exception may be the 45 acp.,it can run in 10mm with a simple barrel swap if it does not have the early extractor.
