My impressions were the 238 was easier to shoot and more accurate, and my wife felt the same. For me, the 938 had a wider pattern that was about 2" low, while the 238 was right on. This is shooting them one after the other and swapping back and forth, so I don't think there was any weird mojo going on.
For comparison, my wife's usual carry is a Ruger SR9c, and mine is a full-size 1911. She's been looking for a more concealable gun to wear somewhere other than her waist, and I've been looking...well...just because! Is gun, must try!
There you go - a mini review while I was going to tell you that Lone Star has both of them to try, if Red's South perchance doesn't.
