Doesn't fit - ProMag Beretta 21A Bobcat 7 Round Pistol Magazine

I should have paid attention to the other reviews. Both of the two mags I purchased jam when about 75% of the way in and you need considerable force to pull it out. I note the reviewer from May 5 2021 put in some effort and did get them to work. I am not sure I want to invest that trouble and am also concerned that if I tamper with them and they still don't work that my return might be rejected.
