I have a Baretta 96 in .40 and am quite well pleased with the performance. Althought I prefer my .45 the .40 has similar ballistics and was to by the hybrid between the 9mm and .45.
Wait, scratch that... lost them both in a rather sudden and tragic boating accident.
I’d rather see the FBI go to all 45GAP......hahahahahahhah!
The 9mm hollowpoints can easily match most 45 ammo but 45 has 1 terrific benefit.
In a SHTF scenario, lead cast 45acp will beat the snot off of lead cast 9mm.
So carry a subcompact 9mm for defense but keep a 45acp still.
