Only know of one of our guys who bought one, and that was the first go-round model, not the current one. Not pleased with the functioning problems he experienced.
He tired of sending it back to SIGARMS, and they finally offered to replace it with a different model of his choice. He chose a P220.
Haven't shot a new version, nor do I personally know anyone who has done so.
I'm conservative when it comes to 1911 platforms.
It needs to work, each and every time I press the trigger ... consistently ... reliably ... and exhibit reasonable inherent accuracy ... that's all I ask.
I prefer to handle, examine and test fire different examples of handguns before I actually spend my own money on one. Being a factory certified LE armorer for different platforms and manufacturers, and a firearms instructor, has helped further expose me to different makes, models and designs. One of the reasons I was originally interested in becoming an armorer ... to learn more about different designs and makes, and be able to work on them if I decided I wanted to personally own examples of them.
I'll reserve forming an opinion on the new GSR's until after I've had an opportunity to handle, examine and fire at least a couple of random examples that come through our range. In the meantime, there are enough other 1911 style models with which I've had sufficient personal experience to make me comfortable and confident when it comes to owning and using them ...
