  1. Magazine tubes worth buying

    Posted by Danny Gonzales on Dec 9th 2018

    These Gen 2 tubes are a great deal and while they state 17 rounds, if you add the Tooless base pad and Grams Engineering spring and follower kit, you will get an easy 20 rounds per mag. It's cost me a total of $111.00 for the 20 round mag. Sure beats the other $130++ mags out there that don't have the Dawson Tooless base pads.

  2. No fitting necessary

    Bought 2 new 40 S&W 140 tubes, checked dimensions and everything was within spec. Installed Grams springs and followers, Taran base pads and I'm able to get 20 reloadable with plenty of room.
