**HELP** Shooting 9 mm ammo out of a 40 caliber magazine

[Huffdaddy]

I have a Glock 22 with a lone wolf conversion 40/9 barrel and have realized that the 40 mags run 9mm ammo thru them fine . Anyone else do this i have been told from other people that this works ? looked it up on youtube and they funtion perfect .

Will this Harm the gun in anyway ???

Can't say it will harm the gun, but I wouldn't use it as a defense weapon.

Not sure, but I wouldn't, just me though,lol....the only mags I'd use different caliber ammo in are the 40/.357, as they are almost the same sized casing.

I have a cousin that does it all the time. He says that he has never had a problem.

It will work just fine. It can't harm the gun either. Worst case scenario is a failure to feed, and most likely that will be on the last round. Maybe a failure to hold open on the last round but even that's a long shot. I used to do it all the time, the only reason I stopped is I bought my wife a dedicated 9 and started buying 9 mags. I rarely had an issue. But as some have said I wouldn't trust it for defense without the dedicated magazines.

It's doable but may not function as 100% as it would. As a range option, I see no issue with it.

the Astra A-75 I recently sold had the magazines marked 9mm/40 so it worked with either one in that particular weapon.

I have both 9mm and .40 mags for my Glocks (only have .40 Glocks) the mags do not seem to care what is stamped on the back. They all function flawlessly

No you can not shoot 9mm out of a .40 barrel
