Iggy42 Posted October 4, 2014 Share Posted October 4, 2014 So I am planning an Open XDm for USPSA, and so I am looking at 170mm mags. Am I correct that the Pistol Gear extensions are my only choice. Anyone know of other options that may be available before spring of 2015? I am planning this to be a winter time build so I am not in a hurry for a 170 mag or 2 Sent from my SCH-I800 using Tapatalk 2 Link to comment Share on other sites More sharing options...
WidowsSon683 Posted October 5, 2014 Share Posted October 5, 2014 As of right now I believe those are the only ones available. Link to comment Share on other sites More sharing options...

RIIID Posted October 5, 2014 Share Posted October 5, 2014 A weld up of two tubes would be the better option, the stock base pad could be used and a Gram's 13 coil spring and his follower will give the max capacity. Rich Link to comment Share on other sites More sharing options...

Reshoot Posted April 7, 2015 Share Posted April 7, 2015 I have been using the Pistol Gear 170mm extensions, in 40 S&W, for 3 years now. Capacity is 25 rounds, with the Gram's spring and follower. The slide will not lock open, on an empty magazine, with the Gram's follower. But then, if I run a mag empty (shooting open) I have screwed up anyhow!
