Let me rephrase that. I have .45s with both 4" and 6" barrels. The 6" is more accurate because of the additional barrel length. I can't speak to the .22 caliber though, but I would think the same principle would apply.You need to stay on point to the OP 1" + 2" (post operation) is still less than the OP was asking about
^ Sig worthy right thereMy extra two inches has been a big advantage for me.
