After having read this, it's probably appropriate to add some more HK data:
When I added the numbers last time, the P30 was the most frequent police pistol in Germany (followed by the Walther P99 variants). But I've already seen that the HK SFP9 is probably overtaking it, maybe it already did (since Bavaria police uses the SFP9). So the SFP9 must be very reliable, too (a pistol is very well tested before it can become a police pistol in Germany). But I don't know exactly about the little differences between the SFP9 and the VP9.
