I am about to order a SVI gun for IPSC Open division, the difficult issue besides which custom serial numbers to choose :-) is length. 4.75 "or 6".
When I have been looking information I find the 6" is easier with iron sights when you get longer line of sight. But in the open class, does it matter? I will choose steel grip so what provides the best balance?
Will the barrel length affect power factor in any significant way? I will load 9mm to major.
