I don't like beaver-tails unless I'm target shooting. If I'm shooting targets with a splinter I'm happy to wear a glove.

Straight grips cramp my wrist when I'm carrying the gun, so I want a relaxed pistol grip.

I don't care how long the barrel is, but I shoot better with longer barrels. 28" is fine by me.

I have no model 21s so I don't have to worry about how they're configured. If I had one though it would have to have two triggers...Geo
