So if anything over 10-rounds are prohibited, most police agencies are violating the law. Since the Sig P-226 is a favorite among agencies and they come standard with a 15-round mag.
I hope the legislature has allocated the funding to replace these mags since the law goes by potential capacity and not what is in the mag.
Sounds like what our department did when they upgraded to .357’s back in the 70’s. People complained so they made us carry .38spl in the Smith’s. Did that for years until we upgraded to semi-auto’s...Sig P226 9mm w/ 15-round mags.
