Why use a 140 ever again?!
The 155 mm mag is obviously between the 140 and 170 with regard to capacity. I comfortably get 4 additional rounds in the 155. However, the capacity isn’t the selling point.. It’s the size of the mag tube that seals the deal. The mag loads faster and more efficiently for me, because there’s more room to get my hand on it when I reload. I’m probably not going to buy another 140 mag. Last but not least, I didn’t have to swap springs or followers with this mag like I typically do when I buy a new magazine. What a score!
