If you cut it I imagine the bottom of the spring won't be held in place by anything like it is on a new mag. The Bart magazine is stiff compared to my regular 20 round colt magazine. Provides a lot more tension than the regular colt. Have people had good luck with the factory bushmaster 450 mag? They're cheap so I figured maybe I'd try one.
Cut the spring. Take a winding off at a time and reassess the resultant tension. You can form it like the original bottom with a strong set of needle nose pliers, but retaining it to the bottom is not necessary. Its all a matter of personal preference. I've told Brett this already but I'm no fan of the side tabs spot welded on just below the top of the mag. I understand what they do but I feel it is unnecessary for successful operation. We all have our opinions. IMHO, those tabs add resistance to the cartridges rising up into place and necessitate more spring tension to overcome the additional resistance. I squeezed mine as close to the mag walls as possible, then polished them and rubbed a little Renaissance wax into them to slicken them up.
