I wouldn't use it. Sell it and buy a 33-round 9mm magazine if you can legally own them where you live.
The highest capacity 9mm Glock magazines you can get in Ohio are G17 magazines with magazine extensions. There are some aftermarket companies who make magazine extensions that you can use on G17 magazines in Ohio.thanks for the info. the mag ordered was a 9mm. the company just sent a .40. i will return it and get the 9mm. 33 rounders are illegal in ohio . thanks again
