On the subject of the P-210, I find a reliable source:
On the negative side is the hammerbite, less then optimum mag catch, and the frames isn't the most durable (except for the improved versions released in later years). Shooting hard swedish surplus ammo will crack the frames fast, but with soft loaded US (non +p or +p+) that shouldn't be a problem.
Swiss RUAG 9x19 ammunition for which the P210 is designed, is loaded at or above SAAMI +P specs. I have no first-hand basis for speculating about the hardness of Swedish surplus ammunition, which has been banned from importation to the U.S., though the Bofors M39B round propelling its 6.80 gram bullet at 480 m/s to achieve a .357 S&W Magnum rating of 783.4 joules or 577.8 foot-pounds and penetrate 50 layers of Kevlar at 50 meters, would inflict a beating on any handgun. However, the P210 appears to be hard to wear out with NATO-spec ammunition. Going by Swiss target shooter reports, its life cycle is over 60,000 rounds, at least twice that of comparable handguns like HK P7 or CZ-75. Håkan Spuhr, a gunsmith in Malmö, Sweden, used to claim on his web page at
http://www.vapensmedjan.com/, that all P210 pistols will eventually develop frame cracks, for which his welding provides a permanent cure. If you have objective information supporting these claims, please share it.
The hammer bite can be easily prevented on the existing P210-6 or P210-5 models by retrofitting either the factory bobbed hammer made to be used with the adjustable sight version of the .22LR conversion kit, or an aftermarket tang extension that attaches with the screw retaining the hammer assembly in these target models of the P210. Bear in mind that the current heavy frame P210-6S and P210-5LS models both come from the factory equipped with a lateral magazine catch and an extended tang.
In summary:
all P210 pistols will eventually develop frame cracks
On the negative side is the hammerbite
