So I'm thinking about getting started in 3-gun. I have only competed in handgun (USPSA, IPSC), but I figured I'd expand my training. I just put a Stoeger M3K in jail, and was wondering which mag extension you guys would recommend. I'm looking at the MOA extension kit. Should I get the 5 round extension or a longer one? The 5 round takes the total capacity to 9+1 and only sticks out about 3/8" past the barrel. Would that be enough or should I add more length for more capacity?
Thanks in advance.
Thanks in advance.
