Hello, I am looking to get start in limited/limited 10 shooting. I was looking at getting either a STI or SVI 40S&W get in. My question is about the SVI Schuemann barrels with the holes in the top such as "Hycomp", "Tribrid II", "Hybricomp", "Hybrid". Are these barrels legal in IPSCs and USPSA limited and limited 10? Also, if they are legal what advangteds do they have over the not holed barrels? Last question, are 6" guns legal for limited / limited 10?
