If you are talking about putting a 40 slide and barrel on 9 frame, then it essential is a .40, not a conversion.

Converting a 40 to 9 using a conversion barrell is a whole different animal.

Please clarify.

What guy at what gunstore?

I would have to look, but I think the 9mm slide bore is two small for the .40 barrel to fit.

Someone check me on this.

I am pretty sure it is barrel/complete slide/ and mags.

You can downcovert with just mags and a conversion barrel.

I've heard that too.

Never done it myself so I don't know from first hand experience.

My philosophy is if I want two calibers, buy two guns. Haha

Post by: nf9648 on December 09, 2011, 06:10:42 AM: .40 barrel wont fit in a 9mm slide and vice versa, the only conversion barrels available step down in caliber, not up. Best bet is to buy a Glock 22.

Post by: kong on December 11, 2011, 09:20:05 PM: Be CAREFUL if you think of or try to do this. There is one additional part in the 40 and 45 cal Glocks as compared to the 9mm Glocks 35 vs 34 or 34 vs 33 parts. I forgot now it was told to me awhile back by a Glock armorer.

There are conversion barrels out there for .40S&W pistols (Glock 22/23/27) that allow you to shoot 9mm WITH the conversion barrel (.40 to 9mm) AND the 9mm magazine. With the conversion barrel you don't need to change the internals.
