I have been carrying, and shooting a first generation Ruger LCP since they became available. Never had a problem hitting the mag release on mine. I did add some length to the magazine just enough to get a little more grip area this was before the availability of the extended base plate or extended magazines. I use a Nemesis pocket holster in the back right pocket so much so that there are wear patterns in all my jeans lol. There may be better choices for concealed carry, but for me it works very well. I did pick up last year the Ruger LCP 2 in 22lr as a cheaper option to practice with.
