I will absolutly avoid buying a microstamped handgun; I am not worried about the hypothetical criminal with the foresight to steal and plant my brass, I am however very worried about the safety of putting cracks into the firing pin.
Call me crazy, I mean I'm no engineer, but it seems to me that putting an engraving (cracks) into the business end of a tiny peice of metal that is going to be ramming other peices of metal at high speed thousands of times per year is just a bad idea.
Safety features that are introduced by the manufacturers' as a voluntariy change to the product, I've got no beef with. Locks, magazine disconects, loaded chamber indicators, quadrupal mega-jumbo-safety systems, and a spary on undercoat to protect the leather seats... Whatever. Some of it I'll buy and even look for in a gun, some of it I'll pass up as the marketing scheme it is.
But microstamping is anathema to me, a) because it is being created by government manadate, b) it seems potentially dangerous, and c) doesn't work.
The libertarian in me hates the government mandate. I don't own a motorcycle, but if I did, I would wear a helmet. However, Michigan's mandatory helmet law annoys the heck out of me.
I like the idea of trigger locks and what-have-you, for safe storage and transport (and small theft deterent)... But it annoys me that Michigan law mandates the sale of a lock with each new handgun.
I can put up with the $5 lock, but there is no way I'd ever put up with microstamping.
Rant endeth.
