After 3-4 years in service I have had both Tuff and Bianchi fall apart on me, so as cited, disposable items. The Tuff products tend to split either down the back or break in the middle, the Bianchi's break horizontally on me. I don't believe the quality of the polymer used or the way it is cured is all that good.
I am carrying the 2 +2 with space to grab them from either end as depicted above. When I put 5 shots plus a speed strip reload on a timer some years ago I decided the 5 rounds in a speed strip reload in a J frame was not really worth that 5th round for me...
