Hi Allen, glad to see you got one of the first revision drums from my shop... just a little back ground to help you "tune" your drum into obedience!.... When reforming the drums to fit, I only press die re-formed, (squeezed) the rear section of the mag tube to make it fit a couple of relatively tight Luger test frames... All that leave the shop fit those frames... on your particular unit, I would slightly squeeze the "wide" area of the feed lip area to make it fit... but, just enough.... Go slow, and work thru the sticking points.... one you have it fitting well, we can go further on the tuning... As Don will tell you, you CAN NOT over polish the inside of the drum mag tube and shell, the more you polish and the smoother it gets, all the better..
.... friction is our enemy??... It may not work right out of the box without some tuning.. but everything is there and it should stand up to any and all use and most abuse?... If you can work thru some of the small issues, it will come around... Also, I will repair or tune the drum for you at no charge, including postage until it works for you to your satisfaction... As long as it has that GT mark you're covered! BTW, use WW white box 115 target ammo for your initial testing?... Keep me in the loop ... and best of luck to all....til....lat'r.....GT.....
