If they were mine personally I would be happy to give you parts. Alas, the parts are owned by my Agency and not mine to sell out individually, we would have to follow standard government agency GAP rules for disposing of them.
As for why the P227 flopped... there were actually some trade-offs for those 2 extra rounds over the P220 (and that 10th round requires near herculean finger strength to force in the mag). At my department, that grip stippling was universally loathed. Our qualification scores went down, and Officers complained that it was more difficult to shoot the P227 well. I personally didn't have this issue... but many complained about it. Also the magazines were a weird dimension, so it was difficult to find open-top mag holders with adequate friction tension to keep spare mags on the duty belt. We had to settle with generic mag pouches with a button flap, which we are trying to get away from. All of this added up, and the consensus was that everyone liked the P220 better. Finally, Glock and 9mm's conquest of the LE market is nigh complete now. Most of the holdouts have finally converted. And honestly it's really hard to argue that there is a better duty pistol than a G17, G19, or G45 in 9mm. Remember LE agencies must look at ease and expense of maintenance, a need for "one size fits all," and other considerations that apply less to individual gun owners.
