What is barrel porting?
Porting is where a series of specially designed small holes are electrically made in the barrels near the muzzle. The barrels are ported for two reasons, both related to recoil: 1) it reduces felt recoil by taking some of the expanding powder gas and “venting” it so it slows/reduces recoil. 2) it reduces “muzzle jump” (where your barrels may jump upward on the shot) so you can recover and get a second shot off quicker. Both issues can be significant factors in your particular shooting. The tradeoffs are that the muzzle blast noise is more noticeable to people standing beside you, and there is a bit of burned powder residue on the barrels and ports that must be cleaned periodically. There is still debate regarding porting, (some love it, some don’t) and it comes down to personal preference.
