Does anybody have any opinions on a P345?

What it lacks in aesthetics, ergonomics, and trigger pull, it makes up for with durability (I actually liked the all steel version better. It was damn near indestructible). For around the same money, there are many 45ACP pistols I would take over the Ruger P345 though. Among them, S&W M&P 45, Beretta PX4, Glock 21SF. Go look in the used shelf at Shore Shot. They always have a few used 45ACP guns. People sell them because the ammo is expensive.
