Anticipating my purchase of a SIG 226, I bought a hi-cap mag before the CA ban in 2000. The store keeper told me that they made great mags.
Months later, after my purchase, I ran some rounds through... I didn't have any misfeeds or anything like that but I did notice that the spring is different on my Ramline than any other I have. Instead of the conventional springs of factory mags, mine has a coil mag and though it worked okay the rounds rattle whenever I get past a certain number (8 I think) but only with every other round I place. I guess its not something I should really be concerned about since it worked fine.
Other than that, I love the magazine. Fits the SIG like a glove, flush with the grips and slides in easy. It doesn't get stuck at the magazine release catch like other mags tend to.
Hope this helps.
P.S.- You got a GREAT name!
