I'd like to put together a reasonable open gun for my next GSSF match, whenever that may be. Currently I have a 19 that I shot in AC, and a 34 that I shot in CD, I also have a 17c that stayed home. My debate is whether to use the 34 or the 17c for the open gun. I want to put a carver mount/c-more on it, but I'm not sure if the angle on the carver mount will be enough to keep the sight safe with the porting. I'd like to keep the 34 for CD, with the longer sight radius I think I'll be better off. Eventually I could find a stripped 34 upper on the for sale boards if I want more length on the unlimited gun. They seem to sell pretty regularly. Also, I could put factory glock c-style porting on my 34 barrel, if I ended up getting a 34 upper for the unlimited gun. Any input would be great.
