Hi Reloader. This is a different part than you're talking about. The extractors with the chamber loaded indicator have a little notch on the end. This one actually looks as though it should go on a larger slide. It's just cut about a 16th of an inch wider all the way across the part. It sticks out whether the chamber is loaded or not. No big deal, but it is another extrusion to catch on a holster or pocket. I believe it's gonna work just fine, but it's not quite right. The only 90 degree part I could find anywhere that was for a 90 degree G17 was the part # SP05509 like this one, although, since the part isn't marked with a #, I can't be sure they sent the right one:
Hi James D. Please let me know what you find out. Didn't you say you used to install head units in cars? If you do, I may have a little side job for you, if you have the time. I'm thinking I need to install a new unit in my son's '04 Grand Prix. His factory unit is crapping out on him. I could probably do it myself, but an expert installation may very well be worthwhile. If we get to that point, I'll PM you to see if you're interested.
Thanks again Guys for all of your help!
