I always liked the "covert" concept myself. So much so that I shortened the grip on a Kahr CW9 to take the PM9 magazines, the 6 rounders are more reliable anyway. Then I put a slide and barrel for a TP9 on it. Made a handy little carry gun. Short grip, 4" barrel.
"Chopped" a G17 to G19 size. Made a better gun
for me. I won't mention what I did to a G41, I'm sure I'd get banned after the furor died down.
Now I just use a P365 and not worry about it. I do find myself wishing Sig would come out with a 4" slide and barrel for it.
The current trend of longer grips is what a lot of people want. The manufacturers wouldn't do it unless there were the customer demand for it. I'm sure there are many people out there that this has helped for their situations. I just hope the pendulum swings the other way and I get that short frame P365 with a 4" slide one day.
