I really like my Walther PPQ M1 .40 but... I felt the 40 hate from the gun community. Calling it a 10mm short helped for a while but I kept having that "I'm no longer a cool kid" feeling.
A friend that worked for Walther (no longer there) even razzed me about having a four-tay & suggested I take a look at Jarvis. Even the Walther booth employees at NRAAM Indy said the conversion barrels worked well. Walther had no plans to offer their own conversion barrel. It was sell it at a loss and buy another PPQ in 9mm or live with the shame.
Feeling the need to rejoin the cool kids, I ordered a 9mm conversion drop-in barrel & two 9mm 15 round M1 mags. I even went threaded (hoping for cool kid+ status)! After a few weeks it showed up in the mail. Nice machining job. Fit was nice.
I do what I always do with a new gun. Let the slide slowly try to cycle a round. See if it'll chamber & go into battery on it's own using the recoil spring. Slowly pull the slide to the rear and see if it'll eject. THIS IS NOT a reliability test. Just something I do to look for possible points of failure. Hollow points hanging up on a feed ramp, incorrect mag feed lip angles, yadda yadda, etc.
The Jarvis conversion barrel failed my slow ejection test. The ejector droped the round early causing a jam. BUT, this was a live round, not just a fired case. Quickly racking the slide worked perfectly, mag after mag after mag.
Live fire testing went well. I ran ~120 rounds using 3 different loads; 115 fmj, 124 gr fmj & 124 gr HST hollow point. Everything functioned perfectly. When doing my part @ 15 yards, accuracy was great. 1 big ragged hole.
I'd recommend this conversion barrel to anyone else that felt left out like me. Nowhere on the gun, does it say .40 S&W. Once you swap in the 9mm conversion, no one will be the wiser. You can say you were always one of the "cool kids". I won't tell anyone if you won't.
