I owned and shot a couple BHPs quite a bit for some years back in the day and have a G48.
Disclaimer: I don't care how a pistol feels but rather how my hands grip it, reach controls and control it in strings of fire. I say this because there are great feeling pistols out there that I find do not quickly index true and run in recoil as lesser feeling guns.
@GJM has posted that Leatham as made this same point - that flat sided guns are superior in respect to these factors. I agree. I categorize Glocks and the HK USP and P7 in this group.
All that out of the way, no I would not say the G48 reminds me of the BHP in the hand. I think it is smaller overall. It provides a very secure and under-control grip for my dominant hand and still plenty of real estate for my support hand to do it's work. It still has the Glock's "squarish" lines and these combined with the smaller dimensions seem to really lock the gun in securely in the grip.
That's my take on it.
