Cybe,<br><br>That's a real helpful review of magazine performance & history. I also like your formula for optimum magazine loads.<br><br>I test extensively any potential defensive ammo for my guns. Some guns are just a lot more finicky than others. In the real world, nothing short of a proven track record of reliability of the individual combination of gun, feeding devices, ammo, & shooter will suffice.<br><br>Thanks,<br><br>John
