Here's how I dressed today proving you can conceal a G23 comfortably OWB during mild summer days. I'm 5'10" 195lbs and have a little bit of a gut, love handles, spare tire...whatever you want to call it. I like wearing my holster at the 9 o'clock position (I'm a lefty) with a straight vertical cant. What I wore: Shirt: Green polo shirt, slightly bigger than normal but not overly baggy, I wear size L polos normally-the polo in the pics is a XL. White t-shirt underneath Pants: 5.11 tactical pants (Also works with any kind of jeans) Belt: 5.11 1.5" web belt (My everyday use gunbelt) Holster: Mitch Rosen Upper Limit-Express Line holster Gun: Glock 23 .40S&W When I asked my wife where my gun was, she identified my right front pocket and thought it was only my Walther PPK. Lifted my shirt and her eyes widened to see my G23 under the polo. Temp today was in the mid to upper 60's which is mild even for WA. I was comfortable all day in this set up running errand with my wife and daughter. You could also wear shorts if the temp was warmer with the same result. Hope this helps some people as it starts getting warmer throughout the country.
