As Far as the Tripp Mags go, try and figure this out. I shot the gun, put maybe 50 rnds throug it, just breaking it in, sighting it in, and chronoing it, every time the slide locked back with 1 left in the mags. Since then, my wife shot about 100, then shot a club match 93, and today shot about 100 more rounds through it, Not once did this malfunction occur. Tripp Figures it is just the difference in how our grip differs. Weird huh? Well he suggested putting his dogleg followers in anyway. Hopefully they show up soon. Nice to know about the metalform option though, thanks.
