I got my Pro match, took it apart, cleaned and lubed it. I have not shot it but I have been handling it to get a feel for it. I am a lefty and the mag release button it very hard to push for me. I have developed a way to curl my finger in and push it over the years. The button is very sharp and the spring is crazy stiff. will a para unit fit or does anyone have any suggestions? a larger button would help me. On a side note the fit and finish of this gun is way better than expected. I would expect this on a real custom gun, The real disappointment is the trigger, Way too much take up, feels like 6lbs but did not measure it but its too much, and the overtravel is not adjusted properly. It should be an easy fix though. Plan is to put a couple hundred rounds through it then do the trigger and have fun with it.
