I’ve been using Prime to purchase handgun safes and see if they work with the T5577 in my NExT. I’ve returned the safes that don’t. lol
I found this Secustar safe that works well with my NExT after performing a small amount of modification. Amazon had a 50% off coupon a couple days ago. This made it only $30.
The safe uses EM4100 tags, similar to the Hornady Rapid safes. The button cover wasn’t allowing me to get a good reading on my NExT. I was able to easily pull the button cover off by unscrewing 2 screws on the inside of the safe. (Same as the Hornady.) I then unscrewed 4 screws to gain access to the RFID antenna. The antenna was attached via a 2 pin JST type connector. I drilled a small hole into the button pad and fed the antenna connector through the hole. I then assembled everything back together and used 3M double-sided tape to attach the antenna to the top of the same.
The safe now opens up quickly with my NExT. I don’t have to move my hand to a specific position and I don’t have to completely touch the antenna.
I do like this safe better than the Hornady Rapid I purchased a few years ago. The antenna is much better, the safe is quieter, and there is a small light on the inside of the safe. The quality and thickness seem to be about the same. I do wish the lock was better. It just uses a simple double-sided key. I might try and switch the lock out later. It will still keep my kids and wife out. haha
