Would like to trade my Gen 4 G17 for a cz75 ....preferably sa but will consider da/sa as well. The glock comes with everything it did new EXCEPT the third magazine as I have lost it. So a total of two magazines. Also comes with the extra backstraps which are still in the sealed bag. Its in excellent condition and am looking for the same on the cz altho its not a deal breaker. Any questions, just ask. Thanks for looking.
