Ok...I've got the picture thing figured out. A couple weeks ago I was asking about wear on my CM9. Little plastic shavings which seem to be normal during break in. I really like this little pistol, but had some concerns, being relatively new to the plastic gun world. I thought it was odd that the little square that I pointed to with my pen was just knocked out. The plastic that is now gone had no function...it just seems odd that they would make the frame with a piece of plastic that would only get knock out after 50 to 100 rounds. Any thoughts?
