scottlep Posted October 30, 2018 Share Posted October 30, 2018 (edited) I thought this might be helpful to some new 1911/2011 builders. I used to just do horrible drawing of the profile of the slide and frame and then note the measurements. Once I found this it has made things a bit easier. Great for taking your measurements before fitting slide and frame. 1911_builders_slide_fitment_sheet.pdf Edited October 30, 2018 by scottlep Link to comment Share on other sites More sharing options...
Aiden Posted October 30, 2018 Share Posted October 30, 2018 Note to self... "before fitting slide and frame" ... Handy chart for sure, thanks! Link to comment Share on other sites More sharing options...
zzt Posted October 30, 2018 Share Posted October 30, 2018 I used a similar chart for my builds. I'd caution against giving much credence to the frame blueprint spec numbers, or the recommendation above. Handle enough new slides and frames and you quickly learn that not everyone machines to GI specs. Also, .002" of play in the slide to frame fir is way too much. You don't need near that much to have a 100% reliable gun. Link to comment Share on other sites More sharing options...
scottlep Posted October 30, 2018 Author Share Posted October 30, 2018 (edited) Yes, I definitely wasn't using any of the "Frame Blue Print Specs" or their recommended tolerances. I was just using the drawing part to note the specs of the parts I am fitting. Considering the sheet was "borrowed" from an 80% 1911 builder site, I wouldn't trust much of what's on it. If you notice it says "Slide Back End View", but the ejector cut is on the wrong side. Which brings me to the next topic.....who in their right mind would want to build an 80% 1911? I have a hard enough time finding consistent quality in the frames and slides from the manufacturers that know what the are doing (supposedly). One pin hole off by .001" and your trigger is crap because the geometry it off. Frame rails cut out of square.....nevermind.....I will leave that discussion for another thread.

zzt Posted October 31, 2018 Share Posted October 31, 2018 Scott, buy your 1911/2011 frames and slides from JEM Guns and you will not have any of those problems. Link to comment Share on other sites More sharing options...
scottlep Posted October 31, 2018 Author Share Posted October 31, 2018 Yes. I agree. I actually have a 1911 slide and frame on the way from them. After the last few builds I have done using STI parts, I am hesitant to use their parts due to the very poor QC. Link to comment Share on other sites More sharing options...
Aiden Posted October 31, 2018 Share Posted October 31, 2018 It's definitely a better approach than mine. I've been scribbling numbers onto painters tape stuck to cardboard boxes on my bench. So either I'm a legit gunsmith or I'm the living proof a man with a dremel should never attempt to build anything. Link to comment Share on other sites More sharing options...
scottlep Posted October 31, 2018 Author Share Posted October 31, 2018 Here is a new version where I removed the specs and recommended tolerances . Download and print the PDF version. 1911_builders_slide_fitment_sheet.pdf Link to comment Share on other sites More sharing options...
