Glock 42 9mm Conversion Kit

A monster ex worked flawlessly until it was sold. Ordered another one. This barrel drop perfectly converts my Model 22 40 cal to Model 17 9mm without any other modifications. Great accuracy. Or I'll never get another one.

Alphawolf Glock 42 Conversion Barrel To 9x18 Makarov

Installed SKU: 1012-STS-A27 9mm barrel conversion on my .40 S&W caliber Glock 22. About 500 rounds through it without a single malfunction. 9mm shot at the same point of aim in .40 caliber. Average group at 7 yards is 3/4 inch.

Ordered the stainless steel version for my G23 and it worked out of the box. Replaced immediately, no problem. I put the oil at the factory recommended level and immediately ran 100 rounds. No problem, no hiccups. Dead on accurate. I already installed the Black Yekes connector and 6lb trigger return spring and man is it a lot of fun to shoot.

Just pop out the old barrel and slide the new one in to fire the 9mm, simple as that. I jammed after trying to get the 19th shot out. Maybe a period break? No problems since shooting 150 rounds now.

It catches on the slide release when installing it- but if you squeeze it a bit, the barrel will move and the slides won't be a problem.

Factory New 9mm Stainless Steel 3.4\

Just got a DD barrel and put it in a G 23 .40 s&w glock and bought a glock 9mm g19 mag.

There are no other modes. I went to the range and shot 50 rounds of S&B 115 1nd 124gr ammo. No FTF or FTE or Stove Pipe or Jam. Works perfectly, very happy with this conversion from 40 to 9mm.

Inspect barrel and finish well before installation. No nicks, scratcjes or dents and the feed ramp was super polished, so smooth feeding. Love can shoot .40 and 9mm from the same g23. This Gen 4 G23 was perfect when the nes were around.

Also less muzzle rise due to the .40 g23's slide being hairier than the g19 9mm slide.
