I'd get a MEC Grabber in the ga of your choice. I have one in 16 ga...love it. Have 4 other presses in the other gauges...all MEC 9000Gs that I have disconnected the auto-advance/gas piston on like Hal4son above mentions. This in essence turns them into a Grabber. If buying new, the Grabber saves you $ or the 9000G.

Good luck with it!
