I agree with the weak cartridge. That seems highly probable especially in the SR22 and similar 'full slide' 22 pistols that's a lot of mass to move and it would be much less tolerant of a "weak" round.
Don't sweat it. .22s are much more likely to have issues.
E-Shock rounds are engineered to expend maximum energy into soft targets, turning the density mass into an expanding rotational cone of NyTrilium matrix particles, causing neurological collapse to the central nervous system.
- Yeah I can do that.
