Another conversion barrel
As some of you may know I have a Glock 20C. I have Lone Wolf barrels in .357 Sig and .40 S&W in addition to a LW 10mm barrel so I can shoot cast bullets.

I just saw that LW now has a 9mm barrel for the G-20. I decided having a 4th caliber would be handy so I ordered the 9mm barrel along with the recommended stainless steel guide rod and 11 lb recoil spring.

Next, .38 Super and 9 X 25

What mag is used in a G20 shooting 9mm?

Believe it or not, the standard mags feed 9mm pretty well. I accidentally got a 9mm round mixed in with some assorted frangible while I was test firing it (with the .40 barrel). Fed just fine, just FTE'd the severly deformed 9mm empty.

I just tried a 9mm round in a G20 mag, and I think I would want to alter a dedicated mag to the conversion.

Link at Lone Wolf, I did not see them. Thanks.

I use g22 mags in my 19 sometimes. it works well for 4 or 5 but once the spring has some pressure on it the feed lips struggle to keep the round in place. Your better off with the right mags

Except there is no such thing as a 9mm mag for a large frame Glock

A 9mm has enough energy to cycle that heavy 20 / 21 slide? I woulda never guessed.

I have a 20 and so far I have a 10mm and .40 LW barrel for it * an the stock barrel that ive never fired.

Did you have to change your recoil spring at all ? that would be an excellent investment for the range cause 9mm is so cheap .

Requires an 11 lb recoil spring and +P ammo according to LW. I can load hot if needed. I already have several thousand rounds loaded to +P levels so I am good.

The LW box came while I was at work yesterday. 2 days USPS from Idaho to Texas, not bad. As expected barrel dropped in and fits fine. Assembled and ran some dummies through. They fed fine from the 10mm mags. Range tomorrow?
