First of all congrats on a fine firearm. I have two and they both shoot and handle great. I found an old El Paso Saddlery holster for mine and it works great. Its a pancake OWB holster that holds it nice and tight to the body. The P228 is a favorite of most shooters. Very accurate and very reliable. You will enjoy it .
