I had to compensate for the unbalanced weight or the nozzle would dive as I squeezed the trigger.
I`ve shot one of their .40S&W models. The bulk really eats up a good bit of the kick and it ran through about 100 rounds with no issues.
I bought one at a local show last year, last hour of the last day so I got it cheap. I personally did not have any mechanical issues with it, after around 200 rounds. One issue I had was the general feel of the gun, it just felt like it was going to fall apart on me. The other issue was the slide weight compared to the frame. I had to compensate for the unbalanced weight or the nozzle would dive as I squeezed the trigger. I know polymer pistols will have unbalanced weight issues but this one was very pronounced. Hope this helps.
