DownUnder Posted December 21, 2021 Share Posted December 21, 2021 Does anyone have pics if they cut/filed their Bul frame to fit STI 2011 mags? Some of my mags go in fine, others catch a bit. Wiggling some of the mags gets the feed lip edge past where it catches on the frame. It looks like I could adapt the mag feed lips, but I am reluctant to do this when the mags are working 100% in STI/SVI frames. If it is a minor change/angle to the lower edge of the frame that may be the way to go. Exploring options at this point and some images would assist. Thanks Link to comment Share on other sites More sharing options...

Thanks I have two BUL 2011s cut to accept STI style 2011 mags. It's pretty simple. Basicly we measured a standard 2011 frame, cheely, and cut the BUL frame to those dimensions. So instead of having full rails for the slide it now look exactly like a standard 2011 frame where the section above the mag opening is. You probably can get away with just opening that area between the rails some with out cutting the sections of the rails out but we didn't try. I'll see if I can get a pic to post.

Bakerjd Posted December 22, 2021 Share Posted December 22, 2021 This is a BUL 2011 commander frame that we also milled to accept standard 2011 grips and installed a cheely grip on. Prasky Gunworks did all the work. Link to comment Share on other sites More sharing options...

Bakerjd Posted December 22, 2021 Share Posted December 22, 2021 If you already have a bunch of standard 2011 mags and want to either do this is have a gunsmith do it it's not a bad idea. Otherwise I would just buy the MBX mags for BUL. Link to comment Share on other sites More sharing options...
