Forgot to add. I have read where people have been having trouble with shells ejecting once fired. The ejector gets stuck and it's a pain to get the spent shell out. I also experienced this problem with mine. I decided to smooth out the ejector thinking if it has rough edges this would help. After taking it about (A pin has to be driven out)I realized what the problem was..........Shavings!!! lots and lots of em! Apparently some guns weren't cleaned very well before assembly and metal shavings found there way into the slot where the ejector slides (under the barrel) I had it apart already so I did do some smoothing of the ejector but I cleaned out the ejector channel real good and I haven't had a single problem since.

If you have one and have had problems with shells ejecting this it the culprit. A simple cleaning will not get this done you need to clean the ejector assembly thoroughly and you may need to take it apart to do so. If you don't want to take it apart then at the very least a high pressure air hose should be used. You will be shocked at the amount of metal shavings that come out.
