WS1, WS2 best M21 chokes ever. Go with the beavertail----only on a 21 though- you'll thank yourself later. 2 trigger or splinter 21's never sell well down the line. All guns get sold someday
I'll second this post. Always look at buying a gun from the stand point of selling it later. Very, very few guns are owned until "death do us part". Go with the WS-1 & WS-2 and the Beavertail on a 21. I am the first to scream when someone says that they just opened the chokes on "their" choke marked barrels, because most likely, it won't be theirs for more than a few short years, if that long.
