Just got an MC9ls, and I am wild about it. Better ergos than my Tacops, better accuracy, better trigger. Recoil is better as well. Just all around a better choice. I am looking forward to trading my Tacops now toward an HK CC9 when they pop up again.
I think the more slim designs, with good grips, ergos, and handling, is the winning formula. Really wish HK, Walther, Beretta, CZ, Glock would embrace this midsize concept.
