I had four new STI 140 mags set up by a rather well known 'smith in Texas. I could only get 18 rounds in and I had to tap them on a table while using a loading tool. Sent them off to Beven Gram for him to work his magic on. Beven reshapes the mags, uses the correct springs and followers and puts his base pad on. I can now load 20 rounds easily and the mags are tuned to perfection and run flawlessly.
