Hi. Just picked up a G17 and will be attending some GSSF events in Southern California soon. So right off the bat do I need to install the 3.5lb connector and pull off my fixed glock sights and install some Dave Sevigny Competition sights? I will probably keep my fixed sights, but how well suited are they for GSSF events? I picked the G17 because I can cover most of the GSSF events with it. Any suggestions would be appreciated. Thanks.
