A lot of the teams (SF) have Glock 19's and 26's, you don't see too many G17's in use. As is known there are other elements in USASOC that also use Glocks, one in specific that previously issued 1911's but now issues Glocks as primary sidearm in various calibers. You can PM if you have any other Q's - have a good week!
