Combo: DAA Dry-Fire Practice Mag, Pack of 3
Just received my package after being on backorder...
This things are great - my normal magazines would take abuse by either falling on the ground or having their feed lips contacting the magwell, causing all the dents in the bottom of it. I would have a single dedicated magazine for insertion on reloads that would double as a Barnie in matches, it would have two dummy rounds on top and I wouldn't care too much about feed lips, but the rest of the magazines would be the ones dropping on the floor. Sure carpet helps, but I would still see the retaining pins on basepads move over time. And, the weight wasn't right. I'm not a big fan of playing with primer-less rounds loaded with my usual bullets. Too much room for error.
These are not metal and feel much gentler on the magwell (when I miss the reload; in reality, I don't care about the magwell, I care about the real magazines). They are also the correct weight (not sure whether it's equivalent of 20 rounds of 180's, but it definitely feels like a loaded magazine). Then, they have what looks like a follower on top and was a bit confusing initially, but then I realized that it's supposed to simulate the top round, with slight springiness to it, to emulate the correct pressure during insert. Makes it quite realistic, similar to what I was doing with dummy rounds.
What's not to like? Solves all the problems.
Disclosure: I have literally just opened the package and tried it out for a while. Unless these magazines fall apart (I train every day) they are worth every penny. Even if they deteriorate after a few months, it would be money well spent.
