Garrison's are great guns to build on, the slide/frame/barrel fits usually very nice and the ones i've seen lately have very good beavertail fits too. They already have good sight cuts. From there it's just adding the extra options you want, plus with the SS version it's easy to refinish after the work.I really like how my SA Garrison turned out. It has accepted upgrades well and is very smooth and enjoyable to shoot. I think it offers a good value for the money and has clean lines.
