while cleaning my .380 I noticed that the lands and grooves don't seem real prominent, is there a way to check them or find a good picture of what they look like in a new gun. ? the bullets go where their aimed so I'm unsure of if I should be concerned.

Mornin tnbersa380owner,
I noticed the same thing on my 9 UC, so I bought another barrel for it and it looks the same as the one I had does.
Plus, like yours,, mine hits where I aim, so I decided not to worry about mine.

Hi Guys, While I was visiting my sister in San Antonio my nephew noticed that about my 9mmUCPro and seemed impressed. He told me his Glocks have the same type of barrel, they are called Polygonal and instead of lands and grooves they have hills and valleys to trap more of the gasses. CZ, Glocks, H&K and Kahrs have the same type of barrels.
