Dry firing shouldn't cause the issue. Quoted from page 17 of the manual:SickSilverado wrote: ↑Thu Sep 05, 2019 7:27 am Just wanted to post the conclusion to this. Ruger replaced my barrel, extractor, and slide. I inspected the gun before shipping it to them and it looks like there was an indentation made on the chamber from dry firing. Guessing that's reason the casings fit so tight in the chamber. No more dry fires without snapcaps for me.
DRY FIRING
Going through the actions of cocking, aiming and pulling the trigger on an unloaded
gun is known as “dry firing.” Dry firing can be useful to learn the “feel” of your
pistol. Be certain that the pistol is fully unloaded (both the chamber and magazine
are empty) and that the pistol is pointing in a safe direction at all times, even when
you are practicing dry firing. The RUGER® SR22® pistols can be dry-fired
without damage to the firing pin or other components as long as the magazine is
inserted.
CAUTION: The RUGER® SR22® pistols cannot fire with the magazine removed.
