I love my G48. Solved the 10 round capacity thing with Shield Arms 15 round magazines. Capacity of a G19 in a thinner and lighter package.
I am probably going to get flamed for this, but here goes anyway:
I can’t help but chuckle at modern shooters that are unwilling, or unable, to adapt to something as relatively minor as different grip ergonomics. Way back when, I wanted a 1911 and picked up a Colt Commander. Trouble was, I am left handed and a stock 1911 is a right handed gun. I didn’t have the money to send it out to have an ambidextrous safety installed (this was in 1979) and that wouldn’t address the magazine release anyway.
I really, really wanted to use that Commander so I did the only logical thing available to me, I trained myself to shoot right handed. Here it is 43 years later and I still shoot and carry all my guns right handed. As a bonus, I am equally as proficient with my left hand.
So, where I am going with this is perhaps take a step back from looking for a gun that is ever so just right, you know, the "Goldilocks syndrome". Instead of complaining about the grip, if you otherwise like a particular gun, teach yourself to adapt to it. It's really not all that hard, I know because if I managed to do it, I am sure that anyone else could do it too.
I have medium sized hands at best, nevertheless I can comfortably shoot various handguns in my collection ranging from a I frame S&W Terrier up to my HK USP.45. I don’t even mind shooting some of my, shall we say more oddball guns like my C96 Mauser.
