AlanHinMN Posted May 20, 2017 Share Posted May 20, 2017 Can anyone tell me if the New style STI 40 S&W 140 mm Tubes with the engraving on the front with Gram spring and Gram Follower fit the USPSA Mag guage? If so will I have room for Skate tape numbers on the bottom? Link to comment Share on other sites More sharing options...
RangerTrace Posted May 20, 2017 Share Posted May 20, 2017 I don't know why it wouldn't.....but I can tell you that the one Grams spring/follower I had wouldn't stay inside the feed lips of the new mags....... Link to comment Share on other sites More sharing options...
ChuckS Posted May 20, 2017 Share Posted May 20, 2017 You really have to use the gauge to know for sure. The tube and what ever basepad you are using will be the main driver. I have never had Grams followers cause a length issue in Para, STI SV or SPS tubes. If the mag is tuned for max capacity, tape can be an issue. Use the gauge.

Did you load the mags full for a day and have the spring "set"? I had that when i first put the grams guts in the sti bodies. Loaded them up full and then unloaded them the next day and that did the trick Link to comment Share on other sites More sharing options...

AlanHinMN Posted May 26, 2017 Author Share Posted May 26, 2017 Ok I converted one of my .40 mags over.... new style sti tube, grams spring, gram follower and tt 4g2 Runs great in my sti edge. 20 reloadable. I can cram 21 in, but don't think it would go in gun. Checked in mag gauge last night. No room for grip tape numbers on bottom. I will have to check on laser ingraving to number them. Thanks everyone. Link to comment Share on other sites More sharing options...
