racerba Posted June 19, 2008 Share Posted June 19, 2008 So by that logic, milling one eleventy-billionth off of the interior of teh slide of my production gun is as appropriate as doing the same off of my extended mag release? Technically, that's not an external modification - so yes, it's legal and you can mill off more if you wish. Heck, you can use a different slide altogether. As long as the weight isn't more than 2 oz over factory weight. Link to comment Share on other sites More sharing options...

As long as the weight isn't more than 2 oz over factory weight. 21 Authorized modifications (Strictly limited to these items and their stated guidelines) •Internal throating and polishing to improve accuracy, reliability and function •Sights – trimmed, adjusted, replaced, colored, or fiber-optic. •Slide – refinishing. Milling of slide – only as required to insert sights. •After-market slides and barrels – provided they are the same length, contour, and caliber as original factory standard. •Grips – Internal beveling. Checkering, stippling, and addition of grip tape or grip sleeves. (see Appendix E4) •Exchange of minor components (springs, safeties, slide stops, guide rods).

Yes, as per vluc's highlights, no more milling, as I discovered to my chagrin after buying a LW slide with front cocking serrations and bevelled rails... (sorry 'bout the drift - I'm still peeved...)

Flexmoney Posted June 19, 2008 Share Posted June 19, 2008 Thanks Flexmoney for clearing things up....Well wouldn't you know, I just noticed two "wear" spots on the corner of my mag catch! Do what you will. Know that it is against the rules. Know that I've worked chrono and I know my way around a Glock. Know that other chrono guys know their way around Glocks. You asked about shooting major matches... Know that I have heard of others calling the rules tighter than I likely would. Good luck. Link to comment Share on other sites More sharing options...

Flexmoney Posted June 19, 2008 Share Posted June 19, 2008 NROI Rulings Title: Aftermarket Slides for Glock's Created: 5/08/08 Updated: 5/20/08 Effective: 5/20/08 Rule number: Appendix D4 item Applies to: Pistol Ruling authority: Director NROI Status: Released Question Is it legal to put a Lone Wolf after market Glock 34 slide and barrel on a Glock 17 and still be legal for Production division? Lone Wolf adds front cocking serrations, a lowered ejection port, a bull nose and is stainless steel. Ruling Glock's do not have the front serrations, an owner of a Glock is not allowed to mill their slide for anything but fitting a sight as per item 21 of Appendix D4, therefore, buying an aftermarket slide that has the front serrations cut into it, does not fit within the guidelines of the original factory contour or standard as specified in the same item.
