The 10mm was just more handgun that I was comfortable shooting. Call me wimp.
The S&W 10s had, deserved or undeserved, a reputation for being less than durable. A large number of them in police service were, apparently, taken bought back by S&W due to cracked frames and other problems due to using the larger round.
The gun I had, a trade-in from a local police department, seemed solid, and that PD had no problem with their guns.
I don't know if the frame problems were widespread, or whether they required a fix, or whether this is another of those handgun "urban myths."
EAA Witness offers a 10mm for about the same price, and I'm really sold on the CZ-7 design (on which it is based); just a small amount gunsmithing should make it into a good gun.
Glock's 10mm, like most Glocks, seems to be nearly indestructible. If I were to do 10mm again, I think I'd go the Glock route, 'cause the polymer frame makes the healthy recoil a little bit easier to tolerate.
And check Georgia Arms for 10mm ammo. Some of the best prices going for quality ammo.
