A few days ago, I went to get a .22 pistol to attach a suppressor to. Looking at several different models, I saw a PPQ .22, the Tactical model (meaning threaded). It felt very close to my 9mm PPQ models, and was reasonably priced, so I bought it. Once home, I realized it fit perfectly in my Blade Tech OWB and JM George appendix holsters.
Got to the range with it this morning, and got it zeroed -- a process made easier by the adjustable rear sight. By the day's end, I have shot 700 rounds through it at steel, Garcia dot drills, Bill drills and accelerators. It was so much fun, that it was hard to stop. Afterwards, I grabbed my 9mm PPQ pistols, and other than realizing I needed to grip them harder, all that work with the .22 was extremely helpful. I then remembered Bill Rogers telling me that after instructing his Beginner class, that involved multiple days of .22 shooting, the next week he would shoot his best scores in his Int/Adv class. He went on to tell me that he would have the Int/Adv class shoot .22, as it is so helpful, but that many Advanced egos would not pay to,go to a class to shoot a .22. When you take the concussion of the centerfire out of the equation, there is nothing to mask trigger imperfections.
I am looking forward to many thousands of rounds of PPQ .22 practice over coming days and weeks.
