i've grown to really appreciate a small gun, i was'nt a big fan of such a small handgun until i picked up my CM9.
i also have the 7rd ext mags that i use & have never had a problem with them, from what i've gathered on the issues members are having useing the ext mags is that there putting to much pressure on the pinky ext causeing the feed issues.
as long as you grip the gun normally you'll be fine, this unit makes for a great edc choice.
i have never pocket carried (jeans), but i do carry inside my jacket pocket & you never know it's there.
you won't be disappointed with the purchase, i was fortunate to pick up a used 1 for $325 with very few rds through it & the breakin was already done.
