Excuse me for my ignorance regarding the advantages or disadvantages between the CZ SP-01# 89152, non-tilted barrel version vs the standard CZ SP-01 #89352, #89353.
Apparently some sellers of these guns specify a "non-tilted barrel" for the # 89152 version.
After doing some research, all of the CZ 75B and SP-01's are "non-tilted barrels", in where the barrel doesn't tip up when pulling back on the slide, like most striker fire guns.
The barrel is considered a "free floating barrel".
