In the 9mm Value Line, it simply isn't fair or accurate to drop the Model 915 in with the 908, 908 and 910. The 915 had a few "spartan" features compared to the regular production 3rd Gens but the 908, 909 and 910 had the less sturdy barrel lock-up, the squared and blocky slide that cost less to machine and the plastic bits that some believe are truly suspect including the magazine catch and guide rod.

The 915 (and 411) are simply BETTER, higher quality pistols than the 908, 909 and 910.
