I just had my friend/FFL deliver my new Sig Sauer P290 in 9mm. I haven't been out to shoot it yet but just can not release the slide with my right thumb. I wonder if that will loosen up or am I just a weakling? And that long long pull of the trigger! Is that a design safety feature for concealed carry? I wish I had looked around a bit more before jumping... I'll admit I'm a handgun novice but I do love quality and can afford to buy it.
