Can I legally use a 3.5# connector in my G17 in stock civilian? I don't know if it qualifies as a part that was ever available from Glock in that model. Thanks.
Yes you can as long as it is a Glock 3.5 connector. In most cases you won't be able to tell the difference between some aftermarket connectors and the Glock one.
WildBill, I asked this question recently and the knowledgable GSSF folks informed me that as long as it is a Glock connector (not aftermarket) you are legal
Wild Bill, if you need a OEM connector try Al Morgan at glockdoc@texas.net inexpensive and quick service! Deter crime SHOOT BACK!
