I've been loving my P320 and its going to become my goto for .... well .... everything. For camping/hiking/backcountry I would like a high capacity 357sig or 40sw option. I've been looking at the Springer extensions and Grams follower setup.
My thought is to setup one of 14rd 357sig/40 mags with the extended base plate setup. I would then use that for my primary 'camping' mag. I would use the mag in either a Compact or Carry frame.
Has anyone use these extension and follower combos?
Is the 140mm length more reliable than the 170mm?
Do they require any modifications to the frame or a specific frame size?
For camping/hiking would people go with the matching black extension or visible red?
