The M11-A1 is basically a 9mm P229 with no rail, phosphated internals, and SRT standard, so yes, the P229 is as good as the M11-A1. If you are actually talking about a P229 Legacy, then it will have an old-school Legacy slide that has the short external extractor and the half-height serrations. A P229 Legion will have the long extractor, full-height serration slide along with a Grayguns P-SAIT trigger.
