I might get my K40 back from the shop this week. In the meantime, I've had a lot of fun with this.... and it fits perfectly into my K40 holster (made for K9/40/CW) , something I never would have guessed. I think I've become more accurate with pistols simply by shooting lots of 22 LR. I don't know why but it's a blast to shoot. My K40 going under the knife has been a blessing in disguise but I can't wait to get it back, such a nice pistol.
