I finished the short 10rd mag last Friday and ran about 700 rounds through it on Sunday. Only a few FTF... I adjust the spring at the range (cut 3 more) and it worked flawless! Going to cut my other 3 this week!

Take it apart


Tape it up


Make the cut - Cut 8 levels of the spring


Don't let your dogs eat the shavings while you go to the bathroom!


2 Ton Epoxy! Vised up and stuck for 8hrs


Sand down the sides and polish it up
