You’ve hit the nail on the head , it has to feel right . Since I’ve gone back to shooting a Miroku mk38 trap , I’m finding I really like the somewhat old fashioned slim pistol grip . It has a nice radius , and everyone who has had a go with it tends to find a comfortable position . Conversely I’m finding that I don’t like the palm swell on my Krieghoff Sporter pistol grip half as much as I used to , same when I use my mate’s 725 pro sport they tend to give just one choice of hold . The only thing to do is spend some time trying guns for “ comfort “ as it’s such a personal choice . Most shooters would let you try their guns at a club shoot if you asked .
