Good or bad? Is it just like the other M&P pistols? Does it have a full sized grip? (I don't want a short Glock 19 type grip for a range & target pistol.) Does it cycle all .22 loads reliably like the new Ruger SR-22 is supposed to do? Can the trigger pull be lightened by buying & installing parts like other M&P's? How long have these been in production?
