MoNsTeR Posted December 17, 2012 Share Posted December 17, 2012 It is no different than cutting a recoil spring. You don't reduce their useful life by 80 %. Of course not, because recoil springs function at a wide range of strengths. I could put a 12-pound recoil spring in my Open gun and run it for years, because it would just get weaker and weaker. It would still work because 11 pounds, 10, 9, 8, 7, maybe even 6 pounds is still enough strength to function. 11-coil (and 13-coil in 170's) mag springs are already on the edge of reliable function right out of the bag. Grams springs in particular will barely last 6 months if you shoot a lot. Unlike a recoil spring, once a mag spring drops below a certain threshold of strength, it stops functioning reliably. Now, perhaps we have differing definitions of "reliable", but in my estimation if a mag spring doesn't work 100% it's time to throw it away. In my experience, cutting coils from these springs will get you from 100% to 99% much, much faster than if you had left them whole. Link to comment Share on other sites More sharing options...
Ming the Merciless Posted December 18, 2012 Share Posted December 18, 2012 Cutting one coil from a Grams or Bolen spring is going to shorten its useful life by 80%+. If it's for a "special occasions only" mag it can be worth it, but if you use it frequently it will lose its reliability very quickly. If the spring is heat treated or deformed past the elacstic or plastic limit of the material, that is what decreases life. Normal cyclic wear will eventually wear out a spring, but the coils will maintain their spring rate regardless of how many coils are in the spring. When you cut the spring coils you can get enough rounds into the mag that the springs are deformed past the elastic limit and they have a pretty short workable life span.

mikeg1005 Posted December 31, 2012 Share Posted December 31, 2012 (edited) Honestly? It sounds like a lot of effort for "maybe" one extra round... and the potential of malfunctions. One jam at a match becuase of you running your mags at the max, will do more bad than any advantage a 22rd mag will give you. As far as 21+1 ones? If you are still maybe having to shave the bottom of your basepad, you can get 21+1 in probably any 140mm. All of my 140mm, with Grams or SV guts will hold 21+1 with an SNL pads. Some will not a little trimming on the basepad, some will not(I run these). In fact, one holds 21+1 with a regular +1 pad. Look up the tuning mag thread on this site, following those instructions really does work. Mike. Edited December 31, 2012 by mikeg1005 Link to comment Share on other sites More sharing options...
Th3Un4givin Posted January 25, 2013 Share Posted January 25, 2013 Does anyone know if the 126mm tube with the DP Para base pad will fit into an edge with a magwell on it? Thanks. Link to comment Share on other sites More sharing options...
wgj3 Posted January 25, 2013 Share Posted January 25, 2013 126 with Para pad does fit standard grip, but I couldnt hardly get 20 in mine. Link to comment Share on other sites More sharing options...
Sudden Death Posted January 26, 2013 Share Posted January 26, 2013 (edited) I have a mag that holds 22 in 40 cal and one in the pipe, so I start with 23 in the gun. And it fits the guage too. I took a mag to work and xrayed it and discovered a few things Edited January 26, 2013 by Sudden Death Link to comment Share on other sites More sharing options...

Sudden Death Posted January 26, 2013 Share Posted January 26, 2013 I see I have someones attention, it is possiable, now keep this in mind it is a mag I do not use all the time, just for certain stages, My buddy Two Shot on here can vouch for me having this mag because now he designs the stages for his match around this mag so I do not have the advantage, which is alright with me, CR speed mag tube, bowln/TT spring and follower, SNL base pad, now I have machined on the base pad so I will let you figure out what I did no that part, I am afraid I will be treading on thin ice if I tell, please understand and think outside the box Link to comment Share on other sites More sharing options...
