Great product - Volquartsen Firearms Magazine Follower Button for Ruger Pistols

I shoot the Steel Challenge. NO Alibi allowed. Installation of "Buttons" has reduced jams by 75%. Magazine function is much smoother. No binding, positive presentation of round to chamber. I can't say enough positive things about this product. I gave 4 to my son, his Ruger hasn't had a jam since. Both of us are using CCCI Standard Velocity 40 gr. Ammo.
