TR Young 175 Posted June 8, 2009 Report Share Posted June 8, 2009 Those of you who have cut down a SureFire mag; do you simply cut through the spring at the same point that you cut through the mag, or is there something else I need to do special with the spring? I need to cut one of mine down to make a legal hunting mag for Ohio. Thanks! Quote Link to post Share on other sites
Moe Zambeak 53 Posted June 8, 2009 Report Share Posted June 8, 2009 I have only cut one of mine from 12 to 8. I didn't touch the spring. I'm not sure of what to do going all the way down to a 2 rounder. I think I would just buy a 2 rounder from CSS before neutering a mag that much. I actually fucked up when I cut mine. I meant to cut it down to 10 rounds. Quote Link to post Share on other sites

ChileRelleno 7,071 Posted June 8, 2009 Report Share Posted June 8, 2009 yeah, when cutting down from 12 to 10-8, ya don't mod the spring. Now going down to 5 rnds or less, I would think ya'd need to mod the spring. I'd be thinking about what the average spring force was for the 8-12, and then use some sort of scale, e.g. fish or trigger pull, to figure how much spring ya need before cutting. I just went ahead and bought a Surefire 2 rnd in case I go outta state. Quote Link to post Share on other sites
A307 0 Posted June 8, 2009 Report Share Posted June 8, 2009 Two ways to go, leave the spring the length it is which leaves you a longer mag and cut the mag tube enough for the entrire spring and two rounds. You bascialy have the same feed situation as the top two rounds in a full length mag. Or cut the spring and the mag which will give you the shortest possible mag length and will feed like the last two rounds in the mag. For a general idea on how much to cut the spring remove it and compare it to the mag tube, if its 3 coils longer than the mag tube then cut the spring to be 3 coils longer than the mag tube cut to hold 2 rounds.

sunnybean 939 Posted June 8, 2009 Report Share Posted June 8, 2009 My factory 2 rounder has 9 loops on the spring...haven't used it yet. Quote Link to post Share on other sites
Moe Zambeak 53 Posted June 8, 2009 Report Share Posted June 8, 2009 9 full loops? Pics? Great info, BTW. This will help me if I ever decide to do this. My factory 2 rounder has 9 loops on the spring...haven't used it yet. Quote Link to post Share on other sites
ChileRelleno 7,071 Posted June 8, 2009 Report Share Posted June 8, 2009 (edited) Mine has 7-8, depending how you count'em. Edited June 8, 2009 by ChileRelleno Quote Link to post Share on other sites
Moe Zambeak 53 Posted June 8, 2009 Report Share Posted June 8, 2009 Mine has seven. Thanks for the pic! Perhaps sunnybean was also counting the loops at the top and bottom. This is why I was asking for pics. Thanks for clearing it up! Quote Link to post Share on other sites
sunnybean 939 Posted June 8, 2009 Report Share Posted June 8, 2009 Yes, I'm counting all of them... Quote Link to post Share on other sites
Moe Zambeak 53 Posted June 8, 2009 Report Share Posted June 8, 2009 Looks like A307 was correct about the 3 loops longer than the mag as well. Quote Link to post Share on other sites
space_weazel 1 Posted June 8, 2009 Report Share Posted June 8, 2009 What about putting a block in the mag that way you have an easy to grip long mag and it is reversible? Quote Link to post Share on other sites
TR Young 175 Posted June 8, 2009 Author Report Share Posted June 8, 2009 Sunny and Chile, thanks a ton for the pictures. That will help me tremendously! Quote Link to post Share on other sites
