That's a very good point. I am still new to handguns so I don't exactly know what I am talking about. I will be trying the 365 very soon however. I will say that the g17 felt like a holding a tall beer can and shot like one tooHow a gun feels in your hand is a non-predictor of how well you will shoot it.
Except in this case, you will probably shoot a 365 better. Again, I"m a Glock fanboy, and I sold my 43 and Gen 5 26 after I bought a 365.
The 365 just plain shoots better than a 43X.
