A 1911 style pistol is one that copies the gun designed by John M. Browning way back when. It's been copied by everybody and usually comes in 45acp caliber. While a Browning High Power is similar to the original design it is not a 1911 style pistol IMO. For one reason the BHP is usually 9mm. Neither is the CZ 75B, another much copied semi auto. The original design is an icon and most would agree the most beautiful semi auto ever.
Saying it's for a more experienced shooter is probably true. A glock is certainly more reliable and easier to operate. I guess guns have been dumbed down over the past twenty years.
