importruleI have this model. The pins are standard pins and they are not interchangeable. I highly suggest getting a different practice lock with changeable pins.
WilsonI agree. Standard pins are very easy to learn even without being able to see them. Being able to alter the pins and incorporate spool pins makes something like this much more worthwhile. If I had to buy one or the other, I'd purchase the one with ONLY spool pins (not offered here right now).
Also, the amazon link posted earlier is the one with spool pins. Thats not what is offered on this drop. The clear practice lock with standard pins on Amazon is CHEAPER than this drop, at $33.89 (free Prime shipping or $35+ purchase). Of course prices fluctuate, and could be different later.
