So, I just picked up a KelTec Sub2000 multimag, put in the Sig mag catch, and tried to run Ramline P226 pre-ban mags in it. Unfortunately the slot for the mag catch on the Ramline is too narrow and the catch won't, well, catch. I either need to carefully widen the slot with a dremel or similar, or re-sell the mags. Anyone have experience cutting a mag catch slot? Any recommendations?
