I have fired 10,179 rounds down my 229 sport. I see no real evidence that the barrel is shot out or in trouble. Frankly I bought another whole top end as a backup just in case but I never expect to use it.
The 357sig is a great round, fun to shoot, accurate, powerful and easy to reload for.
What more can you ask for?
10mm and 357sig, the best things to come along since the 38 super!
