I'm going through the same dilemma as you. I have yet to handle a SIG or CZ, so things might change, but I'm leaning towards the SIG Classic P226 in .22lr first and then pick up the X-Change kit for 9mm, .40 or .357sig later. Personally I love the concept of the GLOCK's no external safeties. The less I have to think about when handling/shooting the better. KISS method is the best method ^.^ I would go for a GLOCK but I didn't like the grip angle of th G17 that I held @.@ had to push my hand uncomfortably down to get the sights lined up proper like... Not for me that. That and I like the heft of metal

anywho, that's just me and hope my rants help
